Exploration the operation method of isolated island micro-grid in the new electric changing

摘要

A new round of electric power system reform for the main body to participate in the market transaction, the chance. Micro power grid as the aggregation of distributed power supply (distributed generation, DG), the effective ways to achieve the DG capacity volatility, stochastic and uncontrolled change, especially under the background of new electric change to microgrid provides a good policy support to participate in market transactions. New electricity to the basic background, this paper studies the operation of the microgrid features and related business, and focuses on analyzing the new electricity island under the change of the microgrid operation characteristic, considering the wind turbines, solar units, fuel cell and energy storage devices and power load of the microgrid model, for the best strategy to achieve internal micro power grid operation structure, the lowest marginal cost, the optimal model in ensuring that the internal network, on the basis of balance between supply and demand, realize the optimal control strategy for micro power grid.
