摘要

针对独立微电网系统中众多的风力发电机组、柴油发电机组和蓄电池储能系统之间的复杂协调控制问题

提出了一种基于对等控制和集中控制相结合的独立微电网混合控制策略。在对等控制方法中

设计了“经济输出功率限制”模块及其算法

改进了柴油发电机组的有功频率特性

提高了多台柴油发电机组并列运行时的经济性和灵活性。基于集中控制的微电网中央控制中心从系统全局的角度对系统中各台风力发电机组和柴油发电机组的解并列、蓄电池储能系统的充放电等离散控制活动进行权衡优化

保证独立微电网系统的经济稳定、灵活高效运行控制。仿真分析了独立微电网系统在不同情况下的运行控制结果

验证了所提方法的有效性。

Abstract

Aiming at the complex coordinated control problems among numerous distributed generators (DGs) of wind turbines (WTs)

diesel generators (DSs) and battery storage system (BT) in an islanded microgrid

a hybrid control strategy combined peer-to-peer control and centralized control is proposed. In peer-to-peer control mode

an “economic output power limit (EOPL)” module and its control algorithm are designed to improve the power and frequency characteristics of DSs

and also improve their economic and flexible property for their parallel operations. The central controller of microgrid central control center (MGCC) implements the whole system optimization for various DGs discrete control activities like start-stop of WTs and DSs

charging-discharging of BT

and ensures economic stability

flexible and efficient operation control of the islanded microgrid. Simulations have shown its operation control performances under various conditions

and results have proved the validity of the proposed method. This work is supported by National High Technology Research and Development Program of China (863 Program) (No. 2014AA052001) and National Natural Science Foundation of China (No. 61273172).
