Abstract

In order to improve the voltage stability margin and convergence speed of the power grid, a regional comprehensive energy time series optimization capacity model is established under the condition of fully considering the multi energy complementarity and load flexibility. The multi energy complementary optimal operation model of regional comprehensive energy system is established, the load flexibility and multi energy complementary characteristics are analyzed, and the robust optimal capacity target of regional comprehensive energy system is set on the basis of considering the load flexibility. From the perspective of time series, an optimized capacity model is constructed, and genetic algorithm is improved to solve the multi-objective optimization model of regional comprehensive energy time series capacity. The experimental results show that this method has good optimization effect, improves the stability margin and convergence speed of power grid voltage, and can find the optimal solution for the established objective function, which effectively improves the effect of capacity determination.
