A probabilistic approach to assess the adequacy of wind and solar energy

摘要

Wind energy will become important source for power generation in the near future followed by solar energy. However, these sources are unstable and variable energy, and behave in a different way to conventional sources. This paper incorporates wind and solar energy in reliability evaluation of generation system as renewable power penetration become increasingly significant. Suitable techniques are used for modeling of wind turbine generator and solar cell generator. The effect of increasing power penetration level on their respective model is studied. Comparative results for wind and solar generation model are presented at different penetration level. Capacity credit is also calculated for each source. The effects of increasing power penetration on the capacity credit values are analyzed. The analysis states that capacity benefit from renewable energy sources (RES) are relatively reducing at higher penetration level.
