A capacity allocation optimization method for hydro-photovoltaic-storage multi-energy complementary power generation system

Abstract

The invention discloses a capacity configuration optimization method of a hydropower-photo-electricity-stored energy multi-energy complementary power generation system. The method comprises power generation capacity configuration optimization and standby capacity configuration optimization on the basis of the power generation capacity configuration optimization. According to the power generation capacity configuration optimization (namely hour-level optimization) is realized by adopting a formula F1 described in the descriptions of the invention; the standby capacity configuration optimization(namely minute-level optimization) is realized by adopting a formula F1 described in the descriptions of the invention; and the capacity configuration optimization strategies of the power generationsystem are determined according to the F1 and F2. With the capacity configuration optimization method of the hydropower-photo-electricity-stored energy multi-energy complementary power generation system adopted, the capacity configuration problem of the hydropower-photo-electricity-stored energy multi-energy complementary power generation system under an off-grid condition is effectively solved, the intermittency and randomness problems of new energy are solved, a coupling relationship between the power generation capacity and standby capacity of the system is considered, and the power supplyreliability of the hydropower-photo-electricity-stored energy multi-energy complementary power generation system under the off-grid condition is significantly improved. Therefore, the method is suitable for being popularized and applied.

Description

technical field [0001] The invention relates to the technical field of energy, in particular to a capacity configuration method of a water-photovoltaic storage multi-energy complementary power generation system. Background technique [0002] At present, the large-scale application of new energy sources such as photovoltaics has alleviated the global energy shortage and environmental pollution problems to a certain extent, but the intermittent and random problems of new energy sources make it impossible to complete the power supply independently, and hydroelectric units and pumped storage units are often configured to compensate Photovoltaic, forming a water-photovoltaic storage multi-energy complementary power generation system. Most of the water-photovoltaic-storage multi-energy hybrid power generation systems are generally built in remote areas far away from the main power grid, and often run offline. It is necessary to consider the inherent characteristics of the system ...
