A method for optimal allocation of power energy in hydropower-rich areas

Abstract

The invention discloses a power energy optimization configuration method for a water and electricity-enriched area. The method comprises the steps of establishing a target function of wind power and photovoltaic power generation installed capacity scale maximization; establishing constraint conditions of a power installed capacity constraint, a fire power safety startup constraint, a conventional power generation device utilization time constraint, a power grid company power purchasing quantity constraint and a power grid company power purchasing and selling income constraint; and solving a linear planning problem composed of the target function and the constraint conditions to obtain a water power installed capacity scale, a fire power installed capacity scale, a wind power installed capacity scale, a photovoltaic power generation installed capacity scale, power grid company purchased water power generation capacity and power grid company purchased fire power generation capacity, thereby realizing scientific optimization configuration of various power supplies of water, fire, wind and photovoltaic power generation. Therefore, the influence of large-scale new energy introduction on conventional power supplies and benefits of power grid companies is avoided, various power supplies and the benefits of the power grid companies are subjected to overall planning and all-round consideration, and scientific quantitative bases are provided for sustainable development of various power supplies and the power grid companies in the aspect of power installed capacity scale planning.

Description

technical field [0001] The invention relates to the technical field of electric energy allocation, in particular to an optimal allocation method of electric energy for areas rich in hydropower. Background technique [0002] In response to the pressure of sustainable energy supply and environmental protection, the government has introduced a series of preferential policies for new energy. In recent years, with the development of science and technology and the encouragement of policies, new energy sources such as wind power and solar photovoltaic power generation have developed rapidly. However, the access of large-scale new energy will have an impact on power grid companies and conventional energy production and operation, especially for areas rich in hydropower, new energy will not only crowd out the living space of thermal power, but also affect the operating efficiency of hydropower and power grid companies. In order to promote the coordinated development of new energy an...

Problems solved by technology

However, the existing power energy allocation methods mainly study technical issues such as new energy site selection, consumption, peak regulation, and system stability, without considering the impact of new energy development scale on power grid companies and conventional energy production and operation, let alone In view of the introduction of a large number of new energy sources in hydropower-rich provinces, an in-depth analysis of the squeeze on the living space of power grid companies and conventional energy sources has been carried out, and the coordinated development of various types of electric energy has not been scientifically optimized from the perspective of operational decision-making.
