Multi-time-scale large-user direct trading power market analog simulation method

Abstract

The invention discloses a multi-time-scale large-user direct trading power market analog simulation method. The method comprises the following steps of at the beginning of a month, collecting large user power consumption characteristic information, a power plant unit price curve and power grid transmission data and brining direct-trading long-term markets where multiple large users and multiple power plants are participated together; using a long-term contract decomposition algorithm to acquire daily electricity load of the large users who participate in the direct trading; establishing and solving a monthly capacity market trading model, and acquiring a maximum capacity per hour of a generator set of each power plant and a possible monthly starting up plan; rolling the solving day-ahead market trading model one day in advance, completing day-ahead trading between the power plants and the larger users and acquiring a power plant unit output curve and a large user daily electricity demand. In the invention, a long-term trading market and a day-ahead trading market of the power plants and the large users can be effectively combined, and direct trading between the power plants and the large users is simulated so that multi-time-scale user direct trading market analog simulation is realized.

Description

Technical field: [0001] The invention relates to a method for simulating and simulating a power market for large users to directly trade. Background technique: [0002] Since the reform of the power investment and financing system and the implementation of the fund-raising policy in China, the power industry has developed rapidly, attracting various funds to raise funds for power generation, changing the past situation where power plants were only invested and constructed by the state, and forming a situation of "many power plants" , many independent power plants emerged, alleviating the power shortage. Independent power plants have no direct interest relationship with the power grid company. When power is in short supply, the power grid company can guarantee a certain number of operating hours for independent power plants; when power is abundant, the power grid company gives priority to power plants related to its own interests, resulting in Unit scheduling is unfair. The ...

Problems solved by technology

Independent power plants have no direct interest relationship with the power grid company. When there is a power shortage, the power grid company can guarantee a certain number of operating hours for independent power plants; when power is abundant, the power grid company gives priority to power plants related to its own interests, resulting in Unit scheduling is unfair, high-efficiency, low-pollution and large-capacity units of new independent power plants cannot be fully operated, and low-efficiency and high-pollution units of old power plants that have interests in the power grid are instead operating at full capacity; at the same time, grid companies prioritize their own interests The associated thermal power plants are connected to the grid, resulting in the phenomenon of water abandonment in high water seasons due to the light load of independent hydropower plants, resulting in conflicts between water and thermal power dispatching
