摘　　要：研究了微网并网的接入方式及控制方法。通过对几种微网并网接口的比较,得出微网经电压源换流器接入配电网的并网方式具有结构紧凑、占地面积小等优点,更符合环保和"绿色电力"的需要。分析了微网并网系统的混成特性,提出利用先进灵活的混成控制方法进行微网并网控制,不仅具有控制算法简单、计算量小、计算速度快、跟踪精度高、动态响应速度快和多目标控制等优点,而且混成控制器易于设计,还具有很强的扩展性。通过Matlab/Simulink/State?ow仿真平台,验证了该微网并网方式和控制方法的正确性和实用性。This paper describes the need for development of integrated micro-grid, introduced the advantages and disadvantages of several kind of integrated interface, Micro-grid access to the distribution network is the best through voltage source converter integration, the way have the structure compact and the area small and so on ,conforms to the environmental protection and ＂the green electric power＂ need; Introduced the concept and the characteristic of hybrid control system, analyzed the hybrid characteristic of the integrated micro-grid system, proposed the use of the advanced and nimble hybrid control method for integrated micro-grid conlxol, the control algorithm of the method is simple, and the computation load is small, the computation speed is quick, the tracking accuracy is high and multi-objective control and so on; moreover ,the design of the hybrid controller is easy ,it also has the very strong extension. Verify the correctness and usability of the theory through the Matlab/Simulink/Stateflow simulation platform finally.
