Production bidding organizational method of virtual power plant in day-ahead market

Abstract

The invention relates to an electric power system and an electric power market, and provides a bidding strategy, and can realize the following aspects: 1, the new energy consumption capability can beimproved, and the problems of "wind abandonment" and "photovoltaic abandonment" can be solved; 2, a day-ahead market bidding scheme can be provided for a VPP operator; and 3, the problems of low quantity of a single distributed power generation unit and poor coordination of multiple distributed power generation units can be solved. A production bidding organizational method of a virtual power plant in a day-ahead market is disclosed; a virtual power plant (VPP) is established by a wind generating set, a photovoltaic power generation unit, electric vehicles and an interruptible load in one dispatching region; by making full advantage of complementation characteristics of wind power and photovoltaic power, and by virtue of the wind and photovoltaic total output fluctuation suppression performance by batteries of the electric vehicles, the demand on the quantity of the electric vehicles can be lowered by adopting the interruptible load, and the VPP can be participated in the day-ahead market bidding; and equivalently, the electric energy production and time combined information of the further 24 time frames, and backup output and time combined information are submitted. The productionbidding organizational method is mainly applied to the electric power system and electric power market occasions.

Description

technical field [0001] The invention relates to an electric power system and an electric power market, in particular, relates to a bidding strategy of a virtual power plant in the day-ahead market. Background technique [0002] 1. Concept of virtual power plant [0003] The concept of virtual power plant (virtual power plant, VPP) has not yet been widely accepted by the academic community. In different literatures, different scholars give definitions according to their own understanding. However, the basic idea is much the same. In terms of time, the virtual power plant was proposed after the smart grid concept. In order to solve the scheduling problem of distributed generation. Specifically, in the traditional power grid, the power generation side is generally a large thermal power plant. In order to achieve the balance between power generation and power consumption in the power system, the dispatching department only needs to control the output of the power generation ...

AI Technical Summary

Problems solved by technology

It is pointed out here that the violation of the constraints in the mathematical model may mean that VPP bears greater economic penalties, or that the battery of electric vehicles is not enough to stabilize the fluctuation of the total output of wind and solar, or that electric vehicles do not meet the charging requirements, etc.
