1、XX大学本科学位论文题目：微电网协调运行控制策略摘要本文主要通过进行了理论研究、仿真平台搭建，研究微电网综合协调控制策略，，仿真结果分析，为后续微电网的深入研究奠定了基础。本文设计了PQ控制器、基于下垂特性的V/f控制器，并对逆变器输出滤波器进行了设计。同时，针对PI控制器的不足，利用模型预测控制方法设计了微网中分布式微电源逆变器的PQ模型预测控制策略和基于下垂特性的V/f模型预测控制策略，并在MATLAB/Simulink中建立了仿真模型，对单个微电源分别采用PI控制和MPC控制时的不同场景进行了分析，证明了MPC控制器的效果。最后，建立了微电网的模型，用风力发电
2、机组、光伏以及蓄电池三种微电源的模型代替直流电压源，并设计相应的控制策略，在MATLAB/Simulink中，搭建了整个系统的模型，分别在风机和光伏阵列出口处配置蓄电池，用于平抑并网功率并在孤岛下提高电压和频率支撑，仿真结果验证了控制策略的可行性。关键词：微电网；综合协调控制；风光储；逆变器；模型预测控制StudyontheCoordinationControlStrategyofWind-Solar-StorageMicro-gridAbstractThispapermainlystudiesthemicro-gridintegratedandcoordinate
