A calculation method of multi-energy complementary capacity index of inter-provincial power grid

Abstract

The present invention proposes a calculation method for inter-provincial power grid multi-energy complementary capability index, which includes the following steps: 1) calculate the annual operation mode under the condition of independent operation of each province, and determine the start-up mode of each province; 3) Determine the positive and negative adjustment capabilities of each province under the condition that the start-up mode of each province remains unchanged; 4) On the basis of the complementarity of start-up in each province , to calculate the complementarity capacity of each province. The above three indicators show the complementarity between provinces from different levels, which not only ensures the independence of the operation of each province, but also realizes the mutual aid between the provinces. The solution method is greatly simplified, the physical meaning is clear, and the operation Simple.

Description

A calculation method of multi-energy complementary capacity index of inter-provincial power grid technical field The present invention relates to the field of power system planning and operation scheduling, in particular to a multi-energy complementary capability of an inter-provincial power grid The calculation method of the indicator. Background technique [0002] In the case of large-scale grid-connected power generation from new energy sources such as wind power and photovoltaics, the complementary operation of multi-provincial power grids is a research hotspot. reason On the coordinated operation of multi-provincial power grids, multiple provinces can be merged into one province for unified optimization solution, but there are the following problems: Question: (1) It is not in line with my country's grid dispatching operation mode with provinces as entities; (2) Multiple provinces are merged into one province to optimize operation It may lead to uneven startup of...

Problems solved by technology

In theory, the coordinated operation of multi-provincial power grids can combine multiple provinces into one province for unified optimization and solution, but there are the following problems: (1) It does not conform to the grid dispatching operation mode in which provinces are entities in my country; (2) Multi-province Merger of regions into one province for optimal operation may lead to uneven start-up of thermal power in various provinces, that is, too much start-up of thermal power in a certain province and too little start-up of thermal power in other provinces; Big
