一种独立微电网及控制策略研究

摘要

提出了一种基于智能控制器的独立微电网系统的组网方式及控制策略。系统采用微网子系统相互连接的方式，进行就地能源管理，通过基于优先级的能量平衡控制策略实现发电、储能与负荷的最优配合。据此构建的微电网系统响应速度快、扩展方便，在提升微电网系统控制性能的同时有效减少了电能在不同微网子系统之间传输过程中的能量损失。%This paper proposed an independent micro-grid system with intelligent controller and its control strategy. The system executed in-place energy management using an interconnected way of micro-grid subsystem. Via energy balance control strategy based on priority, the system realized the optimal coordination of generation, stored energy and loads. The built micro-grid system has fast system response speed and extends conveniently. When the control performance of the micro-grid system is promoted, the energy consumption is effectively reduced in the process of transmission between different micro-grid subsystems.
