A Novel Virtual Power Plant Model with Ito Integral Considering Random Noise of Renewable Energy
摘要
With the renewable energy connected to power grid, the virtual power plant (VPP) faces the uncertainty of new energy output in the dispatching process, which brings certain challenges to power system. Considering the continuous stochastic process of renewable energy, this paper proposes a novel VPP model based on stochastic differential equation. The model includes gas turbine, wind turbine, pumped storage power station and load. Based on the renewable energy grid, the random noise of renewable energy output is included, and the VPP model with Ito integral is constructed. The problem is solved by dividing, summing and seeking the limit of the time interval. The correctness and practicability of the proposed method are verified by real examples.
