Researchof Power Distribiution And Control Method Based On Hybrid Distributed Network In Island Micro-network System

The island microgrid system is an effective supplement to the large power system,which is an effective way to improve the utilization of clean energy, to ensure the reasonable operation of large power grid and protect the environment. This paper mainly studies the islanded microgrid system based on hybrid distributed network based power allocation and control method, in order to ensure the reasonable productivity, micro grid system with wisdom and power to the safe and stable operation of the microgrid large-scale promotion has important theoretical significance and wide practical value.Based on the domestic and foreign Island microgrid technology development and research status of this paper,and based on the micro grid project of Network Service Center South Park area, first introduced the wind power generation, micro grid photovoltaic power generation, energy storage of other subsystems, then the mixed and distributed network based island micro grid system analyzes the control strategy of micro grid, working mode, analysis of energy management mode, the design of micro grid operation, off grid and off grid and switching operation strategy, ensure the micro grid operation and economic optimization of network system, from the net operation is stable and reliable, the final design of hybrid distributed network island micro grid system based on the operating platform architecture and function, and according to the monitoring results, the prediction data and historical data, using a variety of power allocation and effective control strategy, realize the island microgrid reasonable Power allocation and ratio, to improve the utilization of energy in micro grid, to ensure the safety and stable operation of microgrid.
