We are inviting submissions to the Energies Special Issue on “Distributed Renewable Generation”.
In the last decade, the electric energy industry has shown a renewed interest in distributed generation. This new trend has been mainly motivated by advances in generation technologies that have made smaller generating units viable and feasible, along with an increasing awareness of environmental issues. The penetration level of distributed generation units is increasing, and it is expected that this growth will continue over the years to come.
Prospects for a decentralized and renewable-based power generation, eventually displacing conventional power plants, reducing the balancing role of the transmission grid, and shifting intelligence to the distribution grid through the creation of local and regional energy systems, become more and more likely in the near future. The widespread use of distributed generation, renewable technologies, and energy storage at the residential level is a major paradigm shift for the electric energy industry, which has traditionally relied on large centralized power generation, allowing to increase the share of locally- and domestically-produced electricity.
On the one hand, depending on its location and size, it can be beneficial in reducing power losses and increasing the overall efficiency of the power system, enabling the evolution towards a sustainable and smart grid. Distributed renewable generation is also an excellent way to power microgrids, increasing grid resilience through the local ability to deal with an emergency by operating off-grid. On the other hand, new difficulties arise related to stability, voltage control, and power quality issues, among others, which have to be addressed with novel research studies and innovative solutions.
Indeed, integrating massive distributed renewable generation into the grid poses many challenges to the electric energy sector. The uncertainty and variability of solar photovoltaic and wind energy resources adds significant complexity to maintain the security and reliability of the system, so adequate control, operations and planning methodologies and tools are required, as well as demand-side management capabilities. More sophisticated balancing and forecasting tools should also be developed to accommodate renewables intermittency.
The potential benefits, impacts and drawbacks have to the properly ascertained using realistic case studies, advanced simulation studies and/or comprehensive experimental tests, as well as cost-benefit and swot analyses. Hence, this Special Issue aims to address this important area of research related to “Distributed Renewable Generation”.
