Abstract

The invention discloses a light-storage combined power station quotation method in an electric power spot market. According to the technical scheme, the method comprises the steps that three operation modes of an energy storage unit are established; constructing a light-storage combined power station deviation assessment cost calculation model and an energy storage unit operation cost calculation model; according to the three operation modes of the energy storage unit, considering the operation cost of the energy storage unit and the deviation assessment of the photovoltaic-energy storage combined power station, taking the optimal market income of the photovoltaic-energy storage combined power station as a target function, and establishing a quotation strategy model of the photovoltaic-energy storage combined power station participating in the electric power spot market; constructing constraint conditions of the quotation strategy model; and solving the quotation strategy model to obtain energy storage unit optimization parameters. According to the method, the new energy output fluctuation error is reduced, the tracking day-ahead scheduling plan of the new-storage power station is improved, and the income level of the new-storage power station participating in the power market is effectively improved.

Description

technical field [0001] The invention relates to the field of electric power market bidding, in particular to a bidding method for an optical-storage combined power station in an electric power spot market. Background technique [0002] With the proposal of the goal of "carbon peaking and carbon neutrality", it has gradually become the consensus of the society to accelerate the transformation and upgrading of power supply structure and realize the sustainable development of energy. The grid-connected power generation system will become an inevitable trend in the development of new power systems in the future. However, the scientific and effective operation of the power spot market is subject to the problems of power supply and demand, power structure, power grid characteristics, load characteristics, and insufficient flexible adjustment resources. [0003] Energy storage is an effective means to solve the problem of renewable energy grid integration under the environment of ...
