Special Issue Information

Dear Colleagues,

Generation and management of distributed electricity using Fuel Cell (FC) / Renewable Microgrids integrating FC / Electric Hybrid Vehicles represents a challenging and feasible opportunity for the next decade to reduce CO2 emissions if the potential of hydrogen and renewable energy are used effectively using advanced Control Techniques and Energy Management Strategies. Thus, a limitation of global warming to 2 °C can be achieved by replacing fossil fuels with hydrogen-based energy and renewable sources.

Title: Multichemestry active battery balancer with fuzzy logic control
Authors: BOGDAN-ADRIAN ENACHE
Affiliation: Polytechnic University of Bucharest, Romania
Abstract: Battery balancing is a standard practice to improve battery efficiency, especially for Li-Ion batteries. Due to the manufacturing process, there are no two batteries alike, and these differences are causing energy loss in series-connected battery strings. An active battery balancer extracts energy from the cell with the highest energy and delivers it to a nearby cell or the battery module. In this paper, a cell to module battery balancer is developed. The system's key component is a flyback converter with a wide enough voltage input to cover all the Li-Ion batteries and even lead-acid. The flyback converter is controlled by a microcontroller that uses fuzzy logic to improve the converter efficiency. The input variables are the voltages from each cell, the discharge current and the temperature, and the output variables are the balancing period and the current value.

Abstract: The ecological impact of the electricity producing way and the conservation of ecosystems have become decisive environmental factors worldwide. Centralized energy systems have proven to be ineffective in disrupting natural factors, such as storms, earthquakes, tsunamis, etc. The transition from conventional energy sources energy production, a predominant pollutant for the whole world, to the production of energy based on wind energy, solar energy, geother-mal energy, biomass energy, tidal and wave energy is made exclusively on the basis of static power converters. The types of interconnection of the power grid supplied from renewable en-ergy systems can be insular and respectively connected to the centralized power grid through electricity distribution systems. The factors that negatively influence the power grid are mainly the voltage decrease below the minimum limits or the capacity of injection of reactive power in the network. Island networks can include all types of renewable energy, including energy stor-age systems. The stability and robustness of the power grid may be affected by the intermittency and interaction between renewable energy sources. In order to increase the level of penetration of renewable energy in this paper will be presented strategies to control the green power sources. For three-phase autonomous energy systems, the active power control is activated, along with the use of energy storage systems. The development of energy infrastructure in rural areas of the planet is essential to ensure the development of the planet. Recent advances in tech-nology have made the use of micro-grids as an economical solution. Therefore, it becomes im-perative to capitalize on and optimize energy generation through the use of local sources. Moreover, it is necessary to design a micro-grid that integrates renewable energy sources into the power grid. Applications with individual distributed generators can cause very serious problems. In order to use the green potential of distributed generation systems is to adopt a systemic approach whereby generation and associated tasks are treated as a subsystem or as a microgrid. This power flow capacity in insularized power systems has a greater potential for local increase in reliability than that offered by the energy system as a whole. This paper estab-lishes a control strategy that can manage a power grid composed of different Renewable Energy Sources for a local community. Dynamic modeling of the energy system is based on energy models of the microgrid components. It will be highlighted in the new static conversion systems, the proper operation of the grid power converter system in accordance with the required re-quirements: unity power factor, control of active and reactive power, DC link voltage control. Thus, both operation modes of a microgrid will be highlighted through the obtained numerical results. Optimal control of the microgrid is required. The solution found by the authors allows the optimal selection of the energy source depending on the degree of pollution and the load requested by consumers. Nowadays, the implementation of nature-inspired optimization tech-niques attracts a lot of attention, for which conventional solving algorithms fail. This paper pre-sents the optimal control techniques for energy management, so as to achieve both safe and effi-cient operation of microgrids. The authors developed a control strategy for managing stored energy and optimizing the total power consumption of the microgrid at the point of common coupling (PCC), taking into account the restrictions imposed by storage devices, voltage and power limits.

Abstract: Decarbonization of civil air transport requires significant leap in airborne hybridization. As consequence, future more electrical aircraft (MEA) will require a massive amount of power elec-tronic converters and high frequency passive filters. Increase of the embedded electrical power, combined with the electrical network complexification is challenging in terms of both weight and safety. Shared converters and high order passive filters are considered solutions to cope with weight saving. However, the self-oscillating behavior of those filters may interact with the control of the power converters and may not be mitigated throw the filter’s design. Thus, the control shall be able to handle filter’s oscillation. Flatness-based control (FBC) is a good candi-date since it embeds all the dynamic, even non-linear, of the model. The whole state of the sys-tem may be controlled with a reduced set of flat variables and ensure global stability. However, FBC exploits the flatness property of the model which may be difficult to prove with high order systems, or may simply not exist. Moreover, practical implementation may be difficult with high order system within noisy environment. This paper gives various theoretical and practical considerations for the design of flatness-based control applied to a three-phases PWM-rectifier associated with un-damped LCL-filter. Experimental results will be given to compare transient performances and maximum output power capabilities of the flatness-based control with two-loops linear control and passivity-based control.
