The invention discloses a renewable energy grid-connected planning method considering economic cost in a market economic environment, and belongs to the technical field of renewable energy grid-connected operation in a power system. The method comprises steps of describing the time-of-use electricity price based on a linearization technology, and providing an important model basis for the construction of a subsequent target function; a two-stage dynamic expansion optimization model is provided, and grid-connected planning of renewable energy sources is carried out under market economy conditions; giving a specific expression of the dynamic expansion optimization model, and constructing various equality constraint conditions and inequality constraint conditions. The optimal power generationcombination of renewable energy sources and other energy sources is determined through optimization, so that a power grid operation department can reduce the cost and improve the operation reliability and service quality of the power grid under the condition of not reducing the load; investment of a private department on renewable energy sources can be encouraged, the standby capacity of a powergrid is increased, the flexibility of the power grid is enhanced, and the overall economic benefit is maximized.
Description
technical field [0001] The invention belongs to the technical field of grid-connected operation of renewable energy in electric power systems, and in particular relates to a planning method for grid-connected renewable energy considering economic costs in a market economy environment. Background technique [0002] In the power system, in order to reduce operating costs and increase the penetration rate of renewable energy in the power generation mix, it is of great significance to implement expansion from the power source side. In order to reduce greenhouse gas emissions and mitigate the possible risks brought about by changes in fossil fuel prices, governments around the world strongly support investment in renewable energy. At the same time, power grid operators focus on using different power generation technologies to reduce production costs, enhance grid stability, Optimizing backup distribution and ultimately providing economical and reliable power supply to loads.
