Abstract

The invention relates to a micro-grid dynamic optimization scheduling method combined with double master control cooperation and an MPSO algorithm. The micro-grid includes two master control power supplies: a storage battery energy storage system and a diesel generating set, and two non master control power supplies: a wind generating set and a photovoltaic power generation system. The method comprises 1) when the storage battery energy storage system is used as the master control power supply for the micro-grid, an economic scheduling optimization strategy for the system; 2) when the diesel generating set is used as the master control power supply for the micro-grid, an economic scheduling optimization strategy for the system; 3) an improved particle swarm optimization algorithm; and 4) a micro-grid economic scheduling optimization process for double master control cooperation based on the particle swarm optimization algorithm. The micro-grid dynamic optimization scheduling method utilizes the improved particle swarm optimization algorithm to solve an optimization scheduling module, can pursue the target of the optimal operation control mode for the system and the minimum generating cost at the same time, can effectively realize the minimum generating total cost target for economical operation of the micro-grid system and maximum utilization of the renewable energy source, and can improve the economical operation performance of the power-grid.

Description

technical field [0001] The invention belongs to the technical field of micro-grid economic operation, and relates to a micro-grid dynamic optimal scheduling method combined with dual-master cooperation and MPSO algorithm. Background technique [0002] The economic dispatch optimization of the microgrid is a key technology to minimize the total power generation cost of the system by optimizing the deployment of the distributed power combination and its output on the basis of ensuring the stable and reliable operation of the system. Due to the various types of distributed power sources in the micro-grid system, different control characteristics, different operating states and operating costs and other influencing factors, the economic dispatch optimization of micro-grids with multiple distributed power sources is a high-dimensional, multi-dimensional Time-scale, multi-constrained and nonlinear complex dynamic optimization problems. Compared with the traditional large power gr...
