Problems solved by technology

[0004] In the existing technology, on the one hand, most of the scheduling plans are only for water and fire, and hydropower is mostly treated as a fixed output, and the coordination of water and fire is not sufficient; Insufficient consideration is given to the optimization and complementarity between power sources, and it is difficult to solve problems such as water abandonment and wind abandonment

Abstract

The present invention provides a multi-source and multi-cycle generation schedule formulation method. The method comprises the following steps: I, building a medium-term and long-term plan scene; II, building a medium-term and long-term plan model; III, building a day-ahead plan model on the basis of the medium-term and long-term generation schedule; and IV, building a real-time plan model on the basis of new energy consumption. The multi-source and multi-cycle generation schedule formulation method builds a plan formulation method in a whole period consisting of a medium-term and long-term plan formulation method, a day-ahead plan formulation method and a real-time plan formulation method, and solves several key problems in the schedule plan aiming at the features of a power supply in a long-time range.

Description

technical field [0001] The invention relates to a method in the field of power grid dispatching in which multiple types of power sources constitute an electric power system, in particular to a method for planning multi-source and multi-period power generation schemes. Background technique [0002] The power generation plan formulated by the power dispatching center is to make rational use of power generation resources, and on the basis of meeting the electricity demand of power users, ensure the balance of power generation and consumption as much as possible, maintain the stability of the grid frequency, reduce losses, and ensure the safe operation of the grid and reliable power supply. [0003] Since the late 1980s, the development of the electricity market, especially the demand of the day-ahead market, has driven the development of security constraint planning application software. In the field of day-ahead and real-time scheduling at home and abroad in recent years, ther...
