Problems solved by technology

The current research on virtual power plants participating in the bidding optimization of the day-ahead power market lacks a description of the coordination of multi-type and different demand-side resource output characteristics, and does not fully consider the acquisition of different demand-side resources within the bidding subject in the day-ahead market bidding power and bidding power prices. Reasonable Coordinate demand-side resource output to maximize benefits

Embodiment Construction

[0103] In order to better understand the present invention, the following specific examples will further illustrate the present invention:

[0104] An optimal bidding strategy for a virtual power plant to participate in the day-ahead power market includes the following steps:

[0105] S1: After each virtual power plant submits the bidding electricity and electricity price of its demand-side resources, the market clearing model of the dispatch center is constructed with the optimization goal of minimum cost, and the market clearing price and clearing electricity are obtained; the construction of the market clearing model of the dispatch center Specific steps are as follows:

[0106] S11: Each virtual power plant submits the bidding power P of its demand-side resource i i and bid electricity price λ i Afterwards, the dispatch center conducts economic dispatch to obtain the clearing electricity price π d and clearing power g i , assuming that the cleared charge g i ≥0, the o...

Abstract

The invention relates to the technical field of power systems and automation thereof, in particular to an optimized bidding strategy for a virtual power plant participating in the day-ahead power market. According to the invention, the optimized bidding strategy is researched for the participation of the virtual power plant in the day-ahead power market bidding, an optimized bidding model is established, the optimized bidding strategy is provided, and scientific theoretical support is provided for the participation of the virtual power plant in the day-ahead power market in the future. According to the established cost capacity model, the output characteristics of multiple types of different demand side resources in the virtual power plant are fully considered, the generated optimization bidding strategy is considered, the bidding electric quantity and the bidding electricity price of the different demand side resources in the bidding subject in the day-ahead market are considered, andthe superiority of the bidding strategy is embodied.

Description

technical field [0001] The invention relates to the technical field of power systems and automation thereof, in particular to an optimized bidding strategy for a virtual power plant to participate in a day-ahead power market. Background technique [0002] In recent years, intermittent energy such as wind power and solar energy has developed rapidly. With the access of large-scale renewable energy, its randomness and intermittent characteristics have brought certain challenges to the safe and stable operation of the power system. Demand-side resources such as gas turbines, electric vehicles, and flexible loads have developed rapidly because of their flexibility, economy, reliability, and environmental protection characteristics, which can effectively solve the above problems. However, demand-side resources generally have a small capacity and mostly exist in a decentralized form. They are not competitive in the electricity market, and it is urgent to coordinate the emergence o...
