户用风水光直流微电网控制策略与实现

分布式能源、微电网和智能电网都是当前电力行业的热点课题。现有微电网研究集中在并网控制、潮流计算、建模与仿真、拓扑结构与控制等方面，实际投入运营的系统不多。该文在利用现有研究成果基础上，设计并研制了一套面向户用的微电网系统。该系统由风水光等电源、储能蓄电池、逆变器等单元构成，由微网调度器和远程SCADA系统进行监控和调度。通过系统分析、建模仿真和完善的功能设计，实现了智能调度与功率自动平衡、故障自愈和即插即用等功能，并在某农村投入试运行。研究成果对智能电网的智能能量管理和调度控制研究也具有借鉴意义。

Research and implementation of home wind-hydro-solar micro-grid control strategy

Distributed energy, micro-grid and smart grid are hot topics in the field of electric system. Main research subjects are focused on grid-connected control, power flow calculation, modeling and simulation, topology and control and so on, real operation systems are very few. Based on current research results, a set of home micro-grid is designed and developed. This system consists of such units as wind, hydro ,solar power resources, battery and inverter. The micro-grid is monitored and dispatched by micro-grid energy manager and remote SCADA system. Based on system analysis, model building, simulation and operation design, three important functions are achieved, which include intelligent dispatch and power automated balance, plug and play and fault self-cure. This system has been put into operation for test in a village. The research achievements have reference values for energy management and dispatch control of smart grid.
