Challenges and Research Trends of Renewable Energy Power System

Dear Colleagues,

Through the last decade, the power sector has experienced significant changes due to the incessantly swelling load demand, rapid reduction in fossil fuels, and electricity deregulation policies. Furthermore, because of the modern lifestyle, a growing power demand, growth in industrialization, environmental concerns, and the integration of renewable energy sources (RESs), wind and solar energy in power systems has become the expected choice, with fossil fuel reserves anticipated to naturally come to an end in the future. Consequently, alternatives and RESs will have a noteworthy role in the near-future global energy portfolio.

The fabulous advantages of RESs are their no-carbon emission, clean source, plentiful availability, being environmentally friendly, resource conservation, energy security, health benefits, improving social and economic development through potential employment opportunities, energy access, climate change mitigation, etc. However, RES power generation is intermittent in nature and rests upon weather conditions and its characteristic changes at every instant of time. Additionally, with RES integration, there is uncertainty regarding both the supply and demand sides, possibly creating challenges in power systems regarding various issues such as voltage and frequency stability, decline in the system inertia, intermittent generation, high starting costs, low-grade power quality, demand-supply unbalancing and system reliability.

An innovative outlook and novel ideas are needed to alleviate the aforementioned problems to enhance the penetration of RESs in the electric power grid to convert the old-fashioned electricity grids into smart grids. The variety of energy storage system (ESS) technologies requires development and use in power systems. Although, at the same time, the liberalization of energy markets, revised incentives policies and technology upgrading policies are required to generate competition among generation companies to benefit consumers and grid reliability.

We invite papers related to challenges and new research trends in RES-integrated power systems, topics of interest comprising of automatic generation control (AGC), load frequency control, automatic voltage control (AVR), optimal energy storage devices, hydro power plants, distributed generations, smart grids, power quality, energy harvesting, RES integration into the power system, the flexible AC transmission system (FACTS), etc.

The Special Issue aims to divide problems related to the integration of renewable energy sources into both large and small power energy systems. This consideration includes renewable sources’ influence on the intelligent network construction and the energy market design, also assessing the impact of the distributed generation increase on the energy power system’s stability and reliability, the behaviour of distributed generation in the presence of disturbances in the energy system and many other factors. In this Special Issue, we wish to present results of analytical, experimental or numerical studies of scientists from all over the world, which shall become available to a wide audience through the open access journal Energies, helping to solve the abovementioned problems, also potentially benefiting researchers and policy makers worldwide.
