The Determination of Load Profiles and Power Consumptions of Home Appliances

In recent years, the increment of distributed electricity generation based on renewable energy sources and improvement of communication technologies have caused the development of next-generation power grids known as smart grids. The structures of smart grids have bidirectional communication capability and enable the connection of energy generated from distributed sources to any point on the grid. They also support consumers in energy efficiency by creating opportunities for management of power consumption. The information on power consumption and load profiles of home appliances is essential to perform load management in the dwelling accurately. In this study, the power consumption data for all the basic home appliances, utilized in a two-person family in Çankırı, Turkey, was obtained with high resolution in one-second intervals. The detailed power consumption analysis and load profile were executed for each home appliance. The obtained data is not only the average power consumption of each appliance but also characterizes different operating modes or their cycles. In addition, the impact of these devices on home energy management studies and their standby power consumptions were also discussed. The acquired data is an important source to determine the load profile of individual home appliances precisely in home energy management studies. Although the results of this study do not completely reflect the energy consumption behavior of the people who live in this region, they can reveal the trends in load demands based on a real sample and customer consumption behavior of a typical two-person family.


Introduction
Smart grids (SGs) that attract intensive attention are reliable power grids having self-healing ability, comprising the consumers producing their own energy based on renewable energy sources with minimum cost and allowing the use of available infrastructure with full capacity [1][2][3][4].In addition, SGs give the opportunity for consumers to operate demand response programs independently so that the optimal matching between source and load can be spread to each region of the horizontal time axis by considering consumer habits.In the beginning, demand response was supposed as a change in normal consumption demand taking into account the decrease or increase of the electrical energy production [5].Initial demand response programs were used to control loads at peak times in the United States [6].Demand response programs, considered as a power system resource and an essential part of SGs currently, bring economic benefits to the consumers and utility by spreading the consumption of electrical loads to the time axis, and they also enhance the reliability and sustainability of power grids [6,7].In many countries, incentives are given directly or indirectly to encourage the use of demand response programs.Dynamic demand response programs were accepted by the European Union as a strategic tool to achieve three main objectives, which are reducing greenhouse gases by 20%, increasing the energy production based on renewable energy sources by 20%, and increasing energy efficiency by 20% [8].Although the electricity consumed in buildings varies from country to country, it is equal to 30-40% of the total electricity consumption all over the world [9].According to the data by the Turkish Statistical Institute, the electricity which is consumed by houses and commercial and government buildings approximately constitutes 45% of overall energy consumption in Turkey [10].While industrial and commercial buildings make use of demand response opportunities all around the world, the vast majority of residential buildings cannot use these opportunities [11].It is the opinion that dwelling comfort may be reduced and energy consumption habits are the biggest obstacle for the implementation of demand respond programs at homes [12].However, intelligent home energy management systems have gained popularity in recent years with the aim of enhancing the dwelling comfort in parallel with the advances in information and internet technologies [13,14].Therefore, home energy management studies play a crucial role in enabling demand response programs to be used effectively in residences [15].
The determination of residential load profile and electric power consumption has an effect upon the accuracy of demand response studies.Thus, several methods were used to generate the load profile and power consumption of home appliances precisely [16][17][18][19].The bottom-up approach is often used to generate real electricity consumption data of a residence in the literature [20].The most important disadvantage of the bottom-up approach is that it needs the detailed load consumption data [21].To date, in many publications, representative data and statistical averages of the consumption of electrical appliances have been used to overcome this problem.Ref. [22] classified the buildings in Singapore based on their energy consumption and built their mathematical models and load profiles using the bottom-up model.Then, the produced load models were compared with real models and they classified the houses by the number of rooms they had.Abeykoon V. et al. described the electrical home appliances using machine learning algorithms with the information gathered from power consumption data of home appliances with fast and high precision [23].This modeling was accomplished for the vast majority of the devices, but there is a need for more sample consumption and training of the algorithm in order to achieve the same success in the devices that contain complex operating modes.Pipattanasomporn M. et al. specified load profiles based on the power consumption data for the specified home appliances and described the demand management potentials of these loads.Although the major electrical appliances used in the two separate houses were determined as data sources in this study, the number of these appliances can be inadequate as a source for demand response studies.In [17], the monthly power consumption of home appliances was predicted using a multiple regression model.In addition, the effect of seasonal variation on the monthly power consumption was examined.In 2007, the power consumption of home appliances in 72 dwellings was monitored for over two years and the data was recorded in five-minute intervals [24].The results of the study showed that the energy consumption increased by 4.5% in the second year due to an increase in the appliances that were left in standby mode.Munhaw K. et al. designed a measurement and control system for the power consumption of home appliances [25].The developed prototype suggests that home appliances can be controlled effectively by pursuing the electricity tariff prices.The results of literary reviews show that the information based on the load profiles and power consumption of home appliances is used extensively in many fields such as demand management, energy efficiency, determination of load usage trends, etc.
There are few studies focusing on the data for the power consumption and specific load profiles with high resolution of home appliances which is required in many areas.This is the main reason why the standard load profile and the average electricity consumption of home appliances were used in previous years.With the advent of SGs, more realistic load profiles and power consumption data are needed in the distribution system.The main purpose of this work is to meet the detailed power consumption data and describe load profiles of all operating modes of home appliances with different operating modes.In addition, this study aims to demonstrate demand management opportunities and the impact of standby consumption on energy efficiency by analyzing the obtained data.For this Energies 2018, 11, 607 3 of 18 purpose, the power consumption data of 12 different home appliances used by a two-person family living in Çankırı, Turkey was recorded with high time resolution in one-second intervals from October to December 2016.A special measurement system composed of wireless power measurement plugs and a minicomputer was designed.The detailed power consumption of the home appliances was analyzed and the load profiles were created by taking different utilization modes of the devices into account.The obtained data is essential considering they can constitute a complete source of accurate and precise identification of electrical home appliances in residential energy management studies.Therefore, this paper is unique research demonstrating energy use behaviors of a two-person family in the climate and geographical conditions of Çankırı.

detailed power consumption data taking into account the opening of the door of the refrigerator, the change of power consumption was given in Figures 4 and 5.In Figure 5, the timearea of the refrigerator's opening 5 times is considered in detail.On the first opening, the door of the refrigerator was left open for 30 s.After the door was closed again, the refrigerator operated the fan motor for 1 min and expended approximately 4.1 W during this process.When the door was opened for the second time, the duration of opening time was 5 s and the effect on power consumption was measured as 3.84 W/h.The refrigerator's door was opened for 15 s for the third times and the effect on the hourly power consumption was measured as 4.4 W/h.In the fourth and fifth openings of the door, the power consumption was determined as 4.02 W/h and 3.96 W/h, respectively.It was observed that the refrigerator's door was opened 15 times and for 15 s on an average day in this home.According to these assumptions, due to the opening of the door, the refrigerator consumed 0.25 W power for each time and this value corresponded to 3.75 W in the daily power consumption.Washing Machine: The power consumed by the washing machine, which has 8 kg capacity, was measured and recorded in different washing programs.The results showed that consumers needed the washing machine using different washing modes three times in a week with full loads.We firstly investigated the cotton and synthetics wash programs at 40 °C.The duration of this washing program was 2 h and 6 min, and the heater of the machine worked to raise the water temperature to 40 °C during 1/4 of the washing time.Using the heater during operation time, the power consumption was determined as 961.09W and the total power consumption of the machine was recorded as 1064.21W for this washing option.It was easily calculated that the hourly power consumption of the washing machine was 506.77W in washing conditions.It was observed that roughly 90.3% of the power consumption of the washing machine was caused by the water heater.The determination of time period for water heating was acquired from the recorded data.The

Assessment of Energy Consumption
After the power consumption values of the home appliances were recorded with high resolution, the evaluation of the data was made.The usage frequency of each device was recorded daily, weekly, and monthly and their utilization ratios in Table 2 were determined considering the operating frequencies of these devices for November.

Assessment of Energy Consumption
After the power consumption values of the home appliances were recorded with high resolution, the evaluation of the data was made.The usage frequency of each device was recorded daily, weekly, and monthly and their utilization ratios in Table 2 were determined considering the operating frequencies of these devices for November.
where P Measured-StanBy (ID) stands for the power consumption value in the standby mode.The total power consumption of the home appliances is approximately calculated at 99.4 kW for November.The electricity bill in November 2016 showed that the actual power consumption of the dwelling was 124.4 kW and this result proved the measurement accuracy.The difference between the real consumption and the measurement results represents the power needed by lighting, combi boiler, and low-power devices which was excluded.
Table 3 shows the total power consumption of the home appliances for three months.Table 4 shows how the power consumption of each home appliance impacts total power consumption from October to December.When the results from Table 3 were analyzed, the monthly power consumption was calculated as 121.41 kW on average for the family comprising two persons.In addition, to determine how much energy the consumers use at what time of day, a day was allocated 3 parts according to the energy tariff policy applied in Turkey.Considering this classification, the hours between 06.00 am and 17.00 pm were the daylight tariff part, the hours between 17.00 pm and 22.00 pm were the peak tariff part, and the hours between 22.00 pm and 06.00 am were the night tariff part.When the home energy consumption was classified according to the three mentioned parts, it was seen that the daytime consumption amount for November and December was higher than the others and the amount of demand consumption for October was more than the other energy tariff times.In addition, peak usage of the three months took place in December.This result can be attributed to increased combi boiler usage excluded in the test depending on drops in temperature in December.Table 5 indicates how often power is used in energy tariff periods for each month.Finally, the home appliances that consume energy in standby mode were investigated to improve energy efficiency.It was determined that the computer, television, printer, oven, dishwasher, and washing machine consumed energy in standby mode.Figure 20 shows the ratio of total and standby power usage for November 2016.Standby energy use for that month was up to 4.7% of the total energy.pm were the daylight tariff part, the hours between 17.00 pm and 22.00 pm were the peak tariff part, and the hours between 22.00 pm and 06.00 am were the night tariff part.When the home energy consumption was classified according to the three mentioned parts, it was seen that the daytime consumption amount for November and December was higher than the others and the amount of demand consumption for October was more than the other energy tariff times.In addition, peak usage of the three months took place in December.This result can be attributed to increased combi boiler usage excluded in the test depending on drops in temperature in December.Table 5 indicates how often power is used in energy tariff periods for each month.Finally, the home appliances that consume energy in standby mode were investigated to improve energy efficiency.It was determined that the computer, television, printer, oven, dishwasher, and washing machine consumed energy in standby mode.Figure 20 shows the ratio of total and standby power usage for November 2016.Standby energy use for that month was up to 4.7% of the total energy.

Assessment of Demand Side Opportunities
In the triple time electricity tariff, which is one of the two tariff options offered by electricity distribution companies for residences in Turkey, the unit energy price varies according to the hours of the day.In this section, the possibility of using the home appliances at another time of the day is evaluated without sacrificing dwelling comfort in the case of the household using the triple time electricity tariff.Therefore, the home appliances were classified into two groups according to the dwelling comfort.The first group comprised washing machine, dishwasher, and iron deferrable electrical loads, and the second group undeferrable electrical loads, such as television, computer, refrigerator, and others.The results of the classification of the home appliances are given in Table 6.The classification of the electrical loads may vary considering consumer priorities.When Table 6 is examined, approximately 15% of the total power consumption in a month is at the deferrable loads and the consumers can easily plan its usage time without sacrificing dwelling comfort.

Conclusions
In this study, home appliances' realistic load profiles and power consumption data needed by SG studies were constituted with high resolution.For this purpose, the special measurement system, including a wireless smart plug for power measurement and minicomputer, was designed.The power consumption data of 12 different home appliances employed by a two-person family living in Çankırı, Turkey was recorded for three months.By evaluating and observing the obtained data, the working cycles of each home appliance are determined in detail.Energy consumption behavior and power consumption analysis were performed and detailed load profile data for each home appliance was given on a website at http://profil.guctakip.com.To increase energy efficiency, energy-consuming devices in standby mode were detected and their energy consumption was investigated by comparing overall consumption rate.In addition, according to the energy tariff periods employed in Turkey, all consumption data was evaluated.It was determined that about 15% of the total load at home can be shifted taking energy tariffs into account.The main contribution of this study is to create a realistic load profile and power consumption data which can be used by researchers interested in SG studies and power distribution companies.This data educates consumers about energy efficiency by revealing standby power consumption of a real home.It is expected that residential consumers take the opportunities of demand side management and available resources can be employed with optimum capacity.
