Abstract

Aiming at the problem of low accommodation rate of wind and solar energy caused by insufficient adjustment ability of existing energy structure, an economic optimal dispatching model of virtual power plant considering multiple uncertainties is proposed. Considering the uncertainty and correlation of the wind and solar output in virtual power plant, multiple scenarios of wind and light output are constructed using a Latin hypercube sampling method and reduced to derive typical scenarios using an improved iterative self-organizing data analysis algorithm. According to the wind and solar output value obtained from the day-ahead forecast, the dynamic time-of-use electricity price of virtual power plant is formulated to solve the uncertainty of the electricity price, and the demand-side resources are fully mobilized through the price-based demand response under the dynamic time-of-use electricity price. On this basis, an economic optimal dispatching model is established to minimize the total operating cost of the multi-energy complementary virtual power plant in the trading day, and the snow ablation algorithm is used to optimize the model. The simulation results show that the model can improve the economy of multi-energy complementary virtual power plant operation.
