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

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of electric power system scheduling automation, and in particular relates to a spare capacity analysis method under the coordinated scheduling mode of intermittent energy and conventional energy. Background technique [0002] In recent years, energy conservation and emission reduction and curbing climate warming have become a common challenge and an important issue facing the world. The Chinese government attaches great importance to energy conservation and emission reduction in the power industry, and proposes to implement energy-saving power generation dispatching in the power field to improve the energy efficiency of the power industry. Use efficiency, reduce environmental pollution, and promote the adjustment of energy and power structures. This is a major measure for the power industry to implement the scientific development concept and build a socialist harmonious society. It is an inevitable choice for...
