Since the summer, high temperatures above 35 ° C in many places in the country, and high temperatures in multiple cities have continuously appeared. The economic recovery is superimposed with high temperature weather, my country's electricity load increases rapidly, and virtual power plants frequently enter the public vision.

Since the beginning of this year, the "Fourteenth Five -Year Plan" issued by the National Development and Reform Commission and other departments, as well as the "Fourteenth Five -Year Plan" energy power development plan and carbon peak implementation plan released by Tianjin, Beijing, and Shanghai All, all made clear requirements for the development of virtual power plants.

Virtual power plants have attracted attention, and the state has stepped up the layout

What is "virtual power plant"?

"The virtual power plant is not a power plant, but a energy management system. It is installed in the control terminals of large electricians such as factories and other electricians. Under the circumstances, the balance of supply and demand is achieved by accurate control. "Said Yang Kun, executive vice chairman of the China Electric Power Enterprise Federation.

In Changzhou, Jiangsu, an air -conditioning control module in a shopping mall has access to the load control system. After the analysis of the system, it is found that it is the current peak of local power consumption, which needs to reduce the power load to balance the supply and demand of the power grid. After 30 seconds, the system automatically reduced the load of air -conditioning with a power in the commercial complex to 600 kW of 600 kW, and the temperature in the mall only rose by 1 ° C, which did not affect the customer's shopping experience.

According to the past, when a large electric load appears, the traditional solution is to expand power plants on the power supply side, emergency mobilization of backup power generation resources, and strengthen the orderly use of the electrical terminal.

However, if you only use the expansion of the power plant to meet the power consumption demand during the peak period, it may produce huge waste in the downtown period of the electricity consumption, and the suspension of production caused by orderly power consumption will also have a impact on enterprise production. Therefore, virtual power plants have become a new solution to the load for electricity.

The relevant person in charge of the National Energy Administration said that the load was reduced through the response of the demand side, which would have a better effect on the development of the entire power industry.

It is understood that as early as the "Thirteenth Five -Year Plan" period, my country had carried out pilot work of virtual power plants, deployed multiple virtual power plant projects, and obtained many experiences and data. For example, Shanghai established a demonstration project of a commercial building virtual power plant in Huangpu District in 2017. In 2019, the State Grid Jibei Electric Power Company optimized the innovation virtual power plant operation mode and served the Beijing Winter Olympics.

The "Fourteenth Five -Year Plan" Modern Energy System Plan "further proposed that industrial adjustable load, building air -conditioning load, big data center load, user side energy storage, new energy vehicle and grid energy interaction, etc. Essence

In October 2021, the State Council issued the "Carbon and Peak Action Plan before 2030", which proposed to vigorously improve the comprehensive adjustment of the power system, accelerate the flexible adjustment of power construction, guide self -reserved power plants, traditional high -load industrial loads, industrial and commercial interruption loads , Electric vehicle charging networks, virtual power plants and other participation in system adjustment.

Can improve the ability of new energy consumption

Yang Kun said that as a new format and new model of energy intelligence, virtual power plants have a wide range of prospects. In the context of the power grid structure towards cleaning and low -carbon transformation, the development of virtual power plants on promoting the balance of supply and demand of power grids, realizing low -cost distributed energy sources and low -cost connection connection to the network network. It has important practical significance to fully eliminate clean energy power generation and promote green energy transformation.

Experts said that since 2001, European countries have begun to carry out virtual power plants research projects with integrated small and medium -sized distributed power generation units. In recent years, Australia, Japan and other countries have gradually joined the ranks of virtual power plants.

In August 2021, the national key R & D project undertaken by the State Grid Jiangsu Electric Power Co., Ltd., the friendly interactive system of the urban area, and the power grid supply and demand interactive system, extend the accurate control mode of the load to the electric side of the residents. Fill in the valley "and maintain the purpose of maintaining the balance of power supply and demand.

In addition to the role of the "smart butler" of the power, the virtual power plant can also organize them to organize them through intermittently such as photovoltaic and wind power and other new energy sources.

Yuan Yubo, chief engineer of the State Grid Jiangsu Electric Power Co., Ltd., said that virtual power plants can flatten the random volatility of new energy power, improve the utilization rate of new energy, and aggregate, optimize control and management of various distributed energy sources. Provide auxiliary services such as frequency adjustment and peak regulation.

At present, related companies have accelerated the layout. North China Power Grid took the lead in conducting virtual power plants to participate in the auxiliary service market transactions in China. The State Grid Zhejiang Comprehensive Energy Company's smart virtual power plant platform was launched. The virtual power plant platform of Guodian Investment Shenzhen Energy Development Co., Ltd. participated in the power spot market transaction.

Market prospects

Many people in the industry pointed out that the current virtual power plant is still in the initial stage of development.

Wang Peng, Executive Dean of the National Energy Development Strategic Research Institute of North China Electric Power University, said that the clear "dual carbon" goal has opened a new market incremental market for the development of virtual power plants in my country. The industrial chain of the virtual power plant is composed of the upstream basic resources, the midstream digital platform, and the downstream virtual power plant aggregation. According to reports, upstream basic resources can be subdivided into controllable loads, distributed energy, and energy storage systems, such as factory workshops, shopping mall buildings, large electricity equipment, etc. The digital platform of the midstream is part of the core component of the virtual power plant. It is the smart energy control system that can interact with the power dispatch center and the power trading center. The downstream of the industrial chain can provide users with distribution, grid access and marketing services.

Yang Kun believes that with the rapid development of distributed power supply, electric vehicles, energy storage, and micro -power grids, the resource aggregation method of virtual power plants will enable factories and residents to participate in the value creation of virtual power plants and become an important for the energy Internet. form.

"In the context of the" double carbon 'target and the booming new energy industry, virtual power plants will usher in development opportunities. "Wang Peng said.

Wu Peng, an engineer of the National Grid Energy Research Institute, said that virtual power plants can widely aggregate the resources of the user's side and participate in the flexible interaction of the system, which will alleviate the contradiction between supply and demand of the system and promote new energy consumption.
