Abstract

The invention discloses an auxiliary decision-making system for determining a centralized photovoltaic power station installation scale. The system comprises the following steps that: according to a given installation ratio of a power transmission line, a thermal power plant used for peak regulation and a water pumping energy storage power station, obtaining respective construction and operation cost; and comparing an initial ratio with an optimal ratio, and putting forward three possible decision-making advices: 1) solving after delivery capacity is improved, 2) solving after peak regulationcapacity is improved, and 3) giving the centralized photovoltaic power station installation scale according to an optimization result. By use of the system, an optimal scheduling model is constructedto evaluate the proportion of photovoltaic power generation installation, thermal power installation, water pumping energy storage installation and the maximum power of the power transmission line, the implementation of a decision-making scheme is combined to obtain an optimal photovoltaic power station installation scale, so that the terminal power utilization cost of the photovoltaic power generation is lowered, a discarding ratio is lowered, and economic benefits are optimal.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to an auxiliary decision-making system for determining the installed capacity of a centralized photovoltaic power station. Background technique [0002] Although the theoretical research in the field of technical and economic evaluation and optimization is very mature, there are few studies on the application of technical and economic evaluation and optimization methods to the peak regulation and transmission of new energy power systems. China has not yet established an effective framework system for evaluation and optimization of peak shaving and transmission services to fully, scientifically and reasonably reflect whether photovoltaic power generation, peak shaving dispatch and long-distance transmission are reasonable, whether operations are normal, and resource optimal allocation Whether the function works, etc. [0003] If there is no long-distance transmission of phot...
