Multi-stage power supply planning method for maximizing renewable energy utilization

Abstract

The invention discloses a multi-stage power supply planning method for maximizing renewable energy utilization. The method includes: acquiring power supply planning data, system basic technical data,system operation constraint condition data and system operation prediction data; constructing a multi-stage power supply planning model, a power supply planning budget and construction limitation constraint, a system operation basic constraint, a thermal power plant operation constraint, a hydraulic power plant operation constraint, a renewable energy power plant operation constraint, a delivery channel operation constraint and a renewable energy power plant investment portfolio constraint by taking the maximum renewable energy utilization amount as an objective function; and inputting the obtained data into the constructed power supply planning model, performing solving to obtain a power supply planning construction scheme and a renewable energy consumption evaluation result, and carryingout multi-stage power supply planning to realize maximum utilization of renewable energy. According to the method, the defects in a traditional power supply planning method are overcome, the multi-aspect requirements of system operation can be better met, the utilization level of renewable energy sources is greatly improved, and the method has stronger guiding significance for actual constructionof multiple types of power supplies.

Description

technical field [0001] The invention belongs to the technical field of power supply planning, and in particular relates to a multi-stage power supply planning method for maximizing the utilization of renewable energy. Background technique [0002] The random fluctuation of renewable energy power generation has brought huge challenges to the operation and scheduling of the power system. In order to ensure the safe operation of the system and ensure the full consumption of a high proportion of renewable energy, it is necessary to fully Considering the fluctuation and intermittency of renewable energy output, the resulting power planning scheme has sufficient adjustment flexibility. Therefore, there is a need for a multi-stage power planning method that maximizes the utilization of renewable energy, and optimizes the power structure at the planning level to achieve full utilization and accommodation of renewable energy in the system. [0003] In recent decades, related researc...
