Optimal Dispatch of Multi-Energy Power System with High Energy Load Absorbing Blocked Wind and Photovoltaic Power

Abstract

In order to improve the absorption ratio and realize the efficient utilization of renewable energy, a source-load coordinated two-layer optimal dispatching model is established in this paper, which considering the participation of high energy load in absorbing wind power and photovoltaic power (wind-PV power). In the upper-layer optimal model, the minimum system operation cost of the system and the maximum amount of wind-PV power absorption are taken as the objective functions. And an improved Harris Hawks Optimization is adopted to solve the upper-layer model. In the lower-layer optimal model, the high energy load is used to absorb the blocked wind-PV power calculated by the upper-layer model. Finally, by analyzing the dispatching results, it is concluded that the proposed two-layer optimal dispatching model can effectively reduce the total cost of the system. The high energy load enterprises will gain profit while participating in wind-PV power absorption. The simulation verifies the effectiveness of the proposed optimal dispatching model.
