Problems solved by technology

Under the background of the self-operated distribution network, the present invention solves how the main body of the self-operated distribution network will coordinate new energy in the process of planning and operating the distribution network by considering the impact of demand response on the planning of the self-operated distribution network. The allocation of power generation and the mining and management of user-side resources; by considering the "planning-operation" problem of the self-operated distribution network at the same time, a two-layer opportunity constraint model for the combination of distributed power generation and demand response is established, that is, by considering The influence of various factors to achieve the optimal allocation of distributed power in the self-operated distribution network

Abstract

The embodiment of the invention provides a grid-connection configuration method for distributed generation. The method comprises the steps of constructing an upper-layer objective function, wherein the upper-layer objective function aims at maximizing the net income of asset in the whole life cycle and takes the installation position and the capacity of distributed generation as upper-layer decision making variables; constructing a lower-layer objective function, wherein the lower-layer objective function takes the minimum net load peak-valley difference expected value after the distributed generation is consumed as a target and takes the electricity price as a lower-layer decision making variable; and solving the upper-layer objective function and the lower-layer objective function to obtain a target result, and completing configuration of the distributed generation based on the target result. According to the invention, the problem of how to coordinate the configuration of new energypower generation and the mining and management of user side resources in the process of planning and managing the power distribution network by a self-operated power distribution network main body issolved; and a distributed generation and demand response combined double-layer opportunity constraint model is established by simultaneously considering the planning-operation problem of the self-operated power distribution network.

Description

technical field [0001] The invention belongs to the field of distribution network planning, and in particular relates to a distributed power grid-connected configuration method. Background technique [0002] In the existing technology, it is necessary to gradually release the incremental power distribution investment business to qualified market players in accordance with the requirements that are conducive to promoting the construction and development of the distribution network and improving the efficiency of power distribution operations. This means that there will be an independent distribution network operating entity, which is called self-operated distribution network here. In the process of planning and operating the distribution network, the main body of the self-operated distribution network will face the decision-making problem of how to coordinate the allocation of new energy generation and the mining and management of user-side resources to obtain greater compreh...
