Power two-stage interactive optimization scheduling system of virtual power plant in haze environment

Abstract

The invention discloses a power two-stage interactive optimization scheduling system of a virtual power plant in a haze environment, and specifically relates to a distributed energy resource optimization scheduling method. The method comprises the following steps: A, establishing a photovoltaic power generation prediction and load prediction system considering the influence of the haze environment; B, establishing a power system two-stage interactive scheduling system considering a virtual power plant; C, establishing a mathematical model considering two-stage interactive scheduling of the virtual power plant in the haze environment; D, improving the artificial bee colony algorithm; and E, carrying out solving based on an optimization model of the improved artificial bee colony algorithm. With the system, the energy crisis can be effectively relieved, and the environment can be protected. As new energy and the smart grid technology develop, it is difficult for a power system to directly schedule a lot of grid-connected DERs. The embodiment demonstrates the validity of the model and the feasibility of the algorithm, embodies the superiority of the aggregation of various DERs in power system scheduling, proves the influence of the haze environment on photovoltaic output, load prediction and scheduling, and provides a feasible reference for grid optimization scheduling.

Description

technical field [0001] The invention relates to a distributed energy resources optimal dispatching method, in particular to a two-stage interactive optimal dispatching system for electric power of a virtual power plant in a haze environment. Background technique [0002] The ever-increasing demand for electric energy, the increasingly complex grid structure, low energy utilization efficiency, aggravated environmental degradation, and users' high standards for power supply quality have led to the rapid development of new energy technologies and smart grid technologies. With the characteristics of rich resources, renewable, wide distribution and low environmental pollution, new energy has gradually increased its share in the energy market, and smart grid technology has become increasingly mature with the development of information and communication technology. [0003] In this context, distributed energy resources (Distributed Energy Resources, DERs) composed of distributed ge...

In addition, when the "smog" is serious, thermal power plants are subject to government policy constraints, need to reduce output to reduce pollution emissions, and increase pollution treatment costs and pollution penalty costs, thus weakening their advantages in power system dispatching
