Modular microgrid parallel system

以微电网为研究对象,微电网作为分布式发电新的运行方式,能够有效地协调分布式电源与大电网之间的矛盾,因此成为智能电网的重要分支,具有重要的研究意义和实用价值。研究基于储能双向逆变器的微网双模式平滑投切控制策略,实现了运行模式切换暂态过程的平滑过渡。将TI公司的DSP28035单片机作为控制核心,采用主从控制的方式,通过驱动芯片IRS2003S驱动IRFR3410型MOSFET管实现逆变,设计基于模块化的微电网并联系统,所得系统能以数字信号处理(DSP)作为核心控制单元,协调几个逆变单元的输出电流一致,以达到去除环流的目的。

The present research object,microgrid,as the new operation mode of distributed generation can effectively coordinate the contradiction between the distributed power supply and the large power grid.Therefore,it becomes an important branch of the smart grid,which has important research significance and practical value.The smooth switching control strategy with the microgrid dual mode based on the energy storage bidirectional inverter is studied.The DSP28035 single chip microcomputer of the TI company is used as the control core,and the inverter is realized by driving the chip IRS2003S to drive the IRFR3410 type MOSFET tube.A modular microgrid parallel system is designed.The resulting system can take digital signal processing(DSP)as the core control unit and coordinate the output currents of several inverter units to make them consistent to achieve the purpose of removing circulation.
