Distributed power generation scheduling method considering solar thermal and water potential integrated energy storage output

Abstract

The invention provides a distributed power generation scheduling method considering the comprehensive energy storage output of solar thermal and water potential, which belongs to the technical field of distributed power generation scheduling. The upper threshold of the power generation output, and the actual total amount of solar thermal energy storage is greater than the amount of power generated by the solar thermal energy storage side in each sampling period, the solar thermal energy storage output is used; when each sampling period requires the power output from the water potential energy storage side When it is within the preset range that is less than the upper threshold of the water potential power generation output, and the actual water potential energy storage is greater than the power generation that requires the output of the water potential energy storage side in each sampling period, the water potential energy storage output is used; when the above conditions are not met, the solar thermal output is used. With the goal of minimizing the cost of the energy storage side and the water potential comprehensive energy storage side, the optimal solar thermal output and water potential output results are obtained; the invention overcomes the limitation of a single energy storage method on the energy storage side, improves the power consumption capacity, and optimizes the power grid dispatching. structure and cost.

Description

technical field [0001] The invention relates to the technical field of distributed power generation scheduling, in particular to a distributed power generation scheduling method considering the comprehensive energy storage output of solar thermal and water potential. Background technique [0002] The statements in this section merely provide background related to the present disclosure and do not necessarily constitute prior art. [0003] There have been many research results on power generation technology based on clean energy. The results generally point out that wind power generation and photovoltaic power generation depend on natural environment conditions, which are fluctuating, intermittent, uncertain and anti-peak regulation, and only rely on a single type of clean energy. Power generation will lead to unstable operation of the power grid. Nevertheless, the survey also pointed out that in general, photovoltaic output and wind power output have good complementary advan...
