摘　　要：在大力发展可再生能源和储能技术的背景下,孤立电网中常含多种能源发电方式构成的异构电源,其中可再生能源出力的随机性和波动性给系统的安全经济运行带来了巨大挑战。针对孤立电网中的源侧协同控制问题,提出了基于模型预测控制的多时间尺度孤立电网多源协同优化调度策略。构建日前-日内-实时的多时间尺度协同优化调度模型,实现对孤网源侧具有前瞻性的、逐级精细的调控。针对含连续变量和二进制变量的优化模型,采用混合粒子群算法求解。将所提出的模型分别应用到两个孤网系统算例中,通过仿真分析,证明了所提方法保证系统安全经济运行的可行性和有效性。With the development of renewable energy and energy storage technology,there are heterogeneous power sources of multiple energy in the isolated power grid.The randomness and fluctuation of renewable energy bring great challenges to the safe and economic operation of the system.Aiming at the coordinated control of the sources in the isolated power grid,a multi-time scale collaborative optimization strategy of multi-source for isolated power grids based on model predictive control is proposed.A multi-time scale dispatch model of day-ahead,intra-day,real time is constructed to achieve forward-looking and step-by-step regulation of the sources in the isolated grid.A hybrid particle swarm optimization algorithm is used to solve the problem containing continuous variables and binary variables.The proposed model is applied to two isolated systems,through which the feasibility and effectiveness of the proposed method on ensuring the safe and economic operation of the system are proved.
