摘要

Abstract

In this paper

the bi-layer scheduling method for microgrids

based on deep reinforcement learning

is proposed to achieve economic and environmentally friendly operations. First

considering the uncertainty of renewable energy

the framework of day-ahead and intra-day scheduling is established

and the implementation scheme for both price-based and incentive-based demand response (DR) for the flexible load is determined. Then

comprehensively considering the operating characteristics of the microgrid in the day-ahead and intra-day time scales

a bi-layer scheduling model of the microgrid is established. In terms of algorithms

since day-ahead scheduling has no strict requirement for dispatching time

the particle swarm optimization (PSO) algorithm is used to optimize the time-of-use electricity price and distributed power output for the next day. Considering the environmental fluctuations and requirements for rapidity of intra-day online scheduling

the deep reinforcement learning (DRL) algorithm is adopted for optimization. Finally

based on the data from the actual microgrid

the rationality and effectiveness of the proposed scheduling method is verified. The results show that the proposed bi-layer scheduling based on the PSO and DRL algorithms achieves the optimization of scheduling cost and calculation speed

and is suitable for microgrid online scheduling.
