Bidding method for virtual power plant participating in main and auxiliary markets in consideration of risk constraint

Abstract

The invention relates to a bidding method considering risk constraint for a virtual power plant containing an electric vehicle to participate in main and auxiliary markets simultaneously, the virtual power plant comprises an EV, and the method comprises the following steps: determining a transaction scheduling flow of the virtual power plant containing the EV to participate in an electricity market; based on a transaction scheduling process and a risk condition value CVaR theory, establishing a bidding model in which the virtual power plant considering the risk constraint participates in the main and auxiliary markets at the same time; solving a bidding model in which the virtual power plant considering the risk constraint participates in the main and auxiliary markets at the same time; and based on a solution result of the bidding model, reasonably distributing operation benefits obtained by the virtual power plant participating in the main and auxiliary markets, thereby obtaining a bidding scheme that the virtual power plant participates in the main and auxiliary markets at the same time. The invention further discloses a corresponding system, terminal equipment and a computer readable storage medium. A means is provided for the participation of a single demand side resource with a small capacity in the electricity market, the participation of the VPP in the main and auxiliary markets at the same time, and the flexible measurement of the relationship between the risk and the risk income by a VPP operator according to the risk preference degree of the VPP operator.

Description

technical field [0001] The invention relates to the field of optimization of electric vehicle-containing virtual power plants participating in the power market, in particular to a bidding method for electric vehicle-containing virtual power plants to simultaneously participate in main and auxiliary markets taking into account risk constraints. Background technique [0002] In recent years, under the guiding concept of sustainable development, clean energy such as wind power and photovoltaics has developed rapidly, but the uncertainty of wind power and photovoltaic output has brought huge challenges to the safe and stable operation of the power system. In this context, it is necessary to speed up the construction of the auxiliary service market for peak shaving, and to promote the consumption of renewable energy while improving the regulation capability of the power system. Electric vehicles (EVs) are widely used for their energy-saving and zero-emission advantages. According...

Problems solved by technology

Electric vehicles (Electric Vehicle, EV) are widely used due to their energy-saving and zero-emission advantages. According to the Ministry of Industry and Information Technology, the number of EVs in my country may be about 60 million in 2030, and a large number of EVs are connected to the grid. It has improved the utilization rate of resources in my country's power market and accelerated the pace of achieving the "double carbon" goal. However, due to its small capacity and geographical dispersion, single EVs cannot directly participate in the main energy market and auxiliary service market.
