Short-Term Stochastic Modeling of Virtual Power Plants with Inclusion of Wind, Solar and Tidal Generation and Energy Storage

This paper provides a systematic comparison of three prominent Renewable Energy Sources (RESs) namely, wind, solar and tidal in regards to short-term volatility and their impact on the dynamic behavior of power systems. A Virtual Power Plant (VPP) model obtained through the aggregation of wind, solar and tidal generation is proposed. The effect of frequency control provided by wind/tidal turbine frequency controllers and an Energy Storage System (ESS) embedded in such a VPP are also considered. Simulation results indicate that the VPP with ESS is able to increase the reliability of RESs and effectively reduce short-term frequency fluctuations of the grid.
