A micro-grid group scheduling method and system

By acquiring the day-ahead global dispatch plan and analyzing the operational fluctuation signals of sub-microgrids, effective sub-microgrids are selected and prioritized for dispatch. This solves the problem of low dispatch efficiency of microgrid groups when facing renewable energy fluctuations, and achieves rapid system response and improved stability.

Abstract

The application discloses a kind of micro-grid group scheduling method and system, applied to at least including several sub-micro-grid target micro-grid group, method includes: obtaining the day-ahead global scheduling scheme of target micro-grid group;In the process of executing day-ahead global scheduling scheme, the scheduling demand of first sub-micro-grid is determined by analyzing and determining running fluctuation signal;Determine the operation tension degree of second sub-micro-grid in non-fluctuation state;The electrical coupling relationship between first sub-micro-grid and second sub-micro-grid is analyzed based on the network topology of target micro-grid group, to obtain effective second sub-micro-grid by analysis result screening;Based on scheduling demand and operation tension degree, effective second sub-micro-grid is preferentially scheduled, and the scheduling scheme is determined;The power output of each second sub-micro-grid in target micro-grid group is adjusted at least by scheduling scheme.The micro-grid group scheduling method and system provided by the application effectively improve the operation efficiency of micro-grid group.
