Abstract

Abstract: Aiming at the optimization configuration of multi-energy complementary systems including wind power generation, photovoltaic power generation and energy storage systems, this paper proposes a full life cycle optimization configuration method for multi-energy complementary systems considering system interaction with distribution network and demand-side response costs, Constructed a two-layer optimization model: the upper layer performs global optimization with the goal of minimum annual investment cost, and determines the optimal configuration scheme and energy storage output range of the multi-energy complementary system; the lower layer is established with daily operating costs and renewable energy unutilization as the goals. Multi-energy complementary system and multi-objective economic scheduling model is established. Consider independent and grid-connected multi-energy complementary systems respectively. Taking actual scenery data as an example, a calculation example verifies the correctness and effectiveness of the proposed optimization configuration strategy, and quantitatively analyzes the optimization of the operation mode of multi-energy complementary systems. Impact of configuration strategy.

Key words: optimal configuration, multi-energy complementary, economic dispatching, bi-level optimization
