Standby volume analytical method under coordinating dispatch mode of batch-type energy and conventional energy

The invention discloses a standby volume analytical method under a coordinating dispatch mode of batch-type energy and conventional energy. The method comprises the following five steps of calculating a standby past sample data region, obtaining similar cluster time intervals in a planed date, carrying out statics on a forecast output power deviation distribution of each time interval, obtaining a probability density function of the standby volume of wind energy, and calculating a rotation standby volume of a system under the coordinating dispatch mode of the batch-type energy and the conventional energy. With the adoption of the analytical method, according to a consideration of the coordinating dispatch of assembling units of the batch-type energy and the conventional energy, statics and analysis on data of past wind-power operation are carried out to form the current requirement on the rotation standby volume, safety guarantee is provided for the coordinating dispatch of the batch-type energy and the conventional energy, a reasonable standby volume is provided, and the realization of economical requirement on operation of a power system is facilitated. The method has the characteristics of low calculation intensity and strong adaptability, and is more suitable for popularization and application of connecting with dispatch mechanisms with larger power of wind power.
