Problems solved by technology

[0002] With the progress of human civilization, human beings have attached great importance to green and sustainable development. However, the use of fossil energy to generate electricity also emits a large amount of pollutants, which has caused a certain degree of pollution to the ecological environment. Conventional fossil fuels are no longer in line with green concept of development

Embodiment

[0043] For the convenience of description, the relevant technical terms appearing in the specific implementation manner are explained first:

[0044] like figure 1 As shown, the water-photovoltaic storage system mainly includes: small hydropower station, photovoltaic power station, pumped-storage power station, power load and large power grid;

[0045] Among them, the turbines and variable-speed pumping pumps of small hydropower stations, photovoltaic power stations, and pumped-storage power stations are connected to the AC bus; the AC bus is connected to the power load and the large power grid;

[0046] The output energy of the small hydropower station and photovoltaic power station first meets the load energy demand, and the surplus energy is pumped and stored in the pumped storage power station through the variable-speed pumping pump; when the small hydropower station and photovoltaic power station cannot meet the load demand, the pumped storage power station is used for co...

Abstract

The invention discloses a method for optimizing the operation of a water-photovoltaic storage system considering similarity and economic benefits. The maximum matching between the power generation curve and the load is achieved under 24 dimensions of a day, and the cosine similarity is used to describe the difference between the power generation curve and the load curve. At the same time, when the pumped-storage power station participates in the adjustment of the matching degree, the maximization of its own benefit is considered, so as to establish a dual-objective optimization function of similarity and economic benefit. The system dispatcher can select an appropriate operating point in the Pareto curve composed of similarity and economic benefit according to different risk levels, which can not only satisfy the similarity requirement but also ensure the economic benefit of the pumped storage power station. , the system has high stability and economy.

Description

technical field [0001] The invention belongs to the technical field of hybrid new energy, and more particularly relates to a method for optimizing the operation of a water-photovoltaic storage system considering similarity and economic benefits. Background technique [0002] With the progress of human civilization, human beings have attached great importance to green and sustainable development, and the use of fossil energy to generate electricity also discharges a large amount of pollutants, causing a certain degree of pollution to the ecological environment. Conventional fossil fuels are no longer in line with green Development concept. Renewable energy is a kind of clean energy, which can replace the non-renewable fossil fuels that cause serious pollution to the environment, and generate electric energy, so as to meet people's electric energy demand for daily life and social development. The development and utilization of renewable clean energy can not only effectively r...
