Problems solved by technology

Electricity sales companies are the main players in the domestic retail market. In the initial stage of electricity market reform, due to the small number of electricity sales companies and the lack of market awareness of users, the competitiveness among electricity sales companies is limited. Therefore, its business strategy Relatively simple, mainly the price difference between the purchase and sale of electricity, that is, buy low and sell high

Embodiment Construction

[0088]The drawings are for illustrative purposes only, and should not be construed as limitations on this patent; for those skilled in the art, it is understandable that some well-known structures and descriptions thereof in the drawings may be omitted. The positional relationship described in the drawings is for illustrative purposes only, and should not be construed as a limitation on this patent.

[0089] The present invention aims at determining the optimal business strategy of the electricity sales company under the piecewise linear deviation power assessment mechanism, including the following steps:

[0090] S1: Learning from the performance review mechanism (PBR) implemented by foreign regulatory agencies for the reliability of power supply of power distribution companies, a demand-side deviation power assessment mechanism with piecewise linear assessment unit price is proposed;

[0091] S2: Consider the user's wishes, establish an adjustable load response model based o...

Abstract

The invention discloses an optimal operation strategy determination method of an electricity selling company under a piecewise linear deviation electric quantity assessment mechanism. The method comprises the steps of providing a demand side deviation electric quantity assessment mechanism with the assessment unit price being piecewise linear based on a PBR mechanism; considering the willingness of the user, establishing an adjustable load response model, and simulating the response of the user to the interrupt / increase instruction; researching an actual calling strategy of an electricity selling company for the adjustable load based on the established deviation assessment mechanism; analyzing renewable energy electricity purchasing business of the electricity selling company under the additional system, and calculating electricity purchasing and selling profits of the electricity selling company under the deviation assessment mechanism; and establishing an electricity purchasing and selling decision-making model taking the maximization of the comprehensive utility of the risk and the expected income of a single electricity selling company as a target, and solving the model. The operation strategy obtained through optimization of the method can enable an electricity selling company to effectively avoid market risks, reduce deviation electric quantity assessment and improve operation benefits, and has good economical efficiency and practical application value.

Description

technical field [0001] The present invention relates to the technical field of electric power market, and more specifically, relates to a method for determining an optimal business strategy of an electricity sales company under a piecewise linear deviation electric quantity assessment mechanism. Background technique [0002] In recent years, my country has vigorously promoted the reform of the electric power system. However, most provinces and cities in my country have not yet established an electric power spot market. Electricity is the transaction target. The transition from the market supply and demand balance to the system's physical balance is carried out by the preparation of the dispatch plan and real-time regulation, and the deviation between the actual power generation and consumption and the contract power is inevitable. The reasons for deviation electricity mainly include three aspects: system, unit and user, that is, system causes are due to load forecast deviati...
