Method for conveniently judging hydraulic-solar complementary integrated photovoltaic scale under complex power grid

Abstract

The invention discloses a method for conveniently judging a hydraulic-solar complementary integrated photovoltaic scale under a complex power grid. The method comprises the following steps: S1, analyzing or collecting hourly output processes of a hydropower station and a photovoltaic power station in each typical year; S2, collecting and analyzing the sending-out channel scale of the hydropower station; S3, in combination with the water-electricity and sending-out channel attribution hydraulic-solar complementation situation, a hydraulic-solar attribution complementation proportion scheme is formulated to calculate complementary water-electricity and channel capacity used for complementation; S 4, calculating a light abandoning rate; and S5, calculating the photovoltaic absorption rates ofthe photovoltaic installation scale schemes of different scales under the condition of different hydropower incorporation complementation proportions based on the hydropower incorporation complementation proportions and the light abandonment rates until an optimal solution is obtained. The invention provides a method capable of quickly judging whether the hydraulic-solar complementary integratedphotovoltaic scale is proper or not for the condition that whether the photovoltaic scale is reasonable or not is difficult to quickly judge due to many analysis data, various target functions and complex constraint conditions during large-scale photovoltaic grid-connected consumption of a complex power system.

Description

technical field [0001] The invention relates to the technical field of water-light complementary integration research, in particular to a method for conveniently judging the scale of water-light complementary integrated photovoltaics under complex power grids. Background technique [0002] With the increasingly severe global energy crisis and environmental pollution, large-scale development and utilization of clean and renewable energy is an important means to achieve sustainable development of human society. Solar energy resources are clean, renewable, widely distributed, and have large reserves, and are considered to be an ideal substitute for fossil energy. my country is rich in solar energy and other new energy resources, and photovoltaic power generation has great development prospects. At present, my country is the country with the largest installed capacity of photovoltaic power generation in the world, but the photovoltaic output process has the characteristics of "r...

Problems solved by technology

However, due to different objective functions and many constraints, it is necessary to collect a large amount of data, set a large number of parameters and operation modes, and conduct repeated analysis and calculation when determining a reasonable photovoltaic scale for water-solar complementary integration. Multi-party decision-making by enterprises and power grid companies has brought about time and standard judgment confusion. Therefore, it is necessary to find a method that can conveniently and quickly judge the scale of water-solar complementary integrated photovoltaics
