Technical issues of solar- and gas engine based MicroGrids: Assessment on feasibility by using present technologies

摘要

New trends have appeared in the energy industry in the past couple of years, which are completely different from that we had got used to before. The stock of the conventional energy sources is limited, global warming is affecting our daily life already, and the rising energy demand is forcing us to change the old principles of the centralized power generation system. All these three key factors are showing the same way: the integration of the renewable energy sources into the energy supply systems. One of the possible solutions is building MicroGrids, however we will face many technical difficulties. The stability, flexibility and availability will be affected by the new energy production structure. This study is about to observe the main factors like synchronization problems, voltage conditions, frequency fluctuation and immediate demand and production changes; assessing the feasibility if the currently available technologies were used.
