On August 26, the Shenzhen Virtual Power Management Center, the first virtual power plant management center in China, was established, and the term "virtual power plant" entered the public vision again. It is reported that Shenzhen virtual power plants have access to 14 load aggregates, including distributed energy storage, data centers, charging stations, power stations, subway air conditioners and other types of load resources. Internal load adjustment and peak -cutting valleys ensure the safe and stable operation of the power grid and the balanced and efficient use of power resources.

14 load aggregates have been connected to

Shenzhen Power Grid is a typical receiving grid, and it is also one of the urban grids with the largest power supply load density and leading power supply reliability in my country. It serves more than 20 million, showing the significant characteristics of "three highs and one limit" (high load density, high power supply reliability, high -power energy quality requirements, and limited land). From the perspective of economic density and power supply load density, the contradiction between Shenzhen's new energy access instability and guarantee of the protection of power supply reliability is more prominent, and it is necessary to vigorously enhance the interaction capacity of net loads. In April of this year, the representative of the Shenzhen Municipal People's Congress, the party secretary and chairman of the Shenzhen Power Power Supply Bureau of the Southern Power Grid, Tang Shouquan, suggested that the Shenzhen Power Grid should build a network lotus interactive system with a virtual power plant as its core to guide large -scale user resources to regulate user resources Actively participate in system adjustment.

What is "virtual power plant"? Tang Shouquan explained that the so -called "virtual power plant" refers to the use of the energy Internet technology to integrate the power load scattered in the grid in the power grid, gather sand into a tower, and become a load resource with a certain scale and controllable. Virtual power plants are like an "invisible power plant" that can participate in power balance, improve the efficiency of electricity resources, promote renewable energy consumption and effective use, and large -scale applications can release land resources for Shenzhen.

On the morning of August 26, the Shenzhen Virtual Power Management Center held a unveiling ceremony. This is the first domestic virtual power plant management center, marking the new stage of Shenzhen virtual power plant entering the rapid development. Shenzhen Virtual Power Plant Management Center is located at the Shenzhen Power Supply Bureau of Southern Power Grid. It is managed by the Shenzhen Development and Reform Commission. It is mainly responsible for the construction and daily operation and maintenance of the virtual power plant management platform. , Resource access, commissioning management, receiving and execution dispatch instructions, response monitoring, effect evaluation and other work.

The Shenzhen Power Supply Bureau of Southern Power Grid has carried out demand -side management through the virtual power plant to achieve the functions of the grid peak -cutting valley, realizing the large -scale urban grid peak valley, tight local power supply, and the large -scale occupation of power supply construction in the power grid question. As of July 31, Shenzhen Virtual Power Plant has access to 14 types of load aggregates such as charging piles, energy storage, building buildings, distributed photovoltaic, tap water plant industrial load, ice storage concentration and cooling station, a total of 223 electricity resources 682 distributed photovoltaic resources, the access load capacity is about 655 MW, the photovoltaic capacity is about 215 MW, the total capacity is 870 MW, the maximum adjustable load capacity is 150 MW, and the online rate is more than 95%.

Provide replication experience nationwide

What are the high -tech of Shenzhen virtual power plant? According to the introduction of the Shenzhen Power Supply Bureau of Southern Power Grid, Shenzhen has now been completed and established the first domestic network -level dispatching cloud and can realize the two -level network -level network -level network integrated virtual power plant operation management cloud platform (hereinafter referred to as the "virtual power plant platform" ), The first creation through the APN 4G/5G wireless special network and innovation adopting the industrial Internet of Things cloud tube edge architecture to solve the problem of dispatching and dispatching security for massive load -side resource access to the security problem, and realize the considerable, measured, and controllable user flexible resources.

It is reported that the Shenzhen virtual power plant took the lead in exploring the sustainable development path of "source with the lotus" under the new power system, which is at a leading level in China. Related research results can be promoted to the construction of virtual power plants, large -scale electric vehicles, and new energy storage models, operating simulation, and optimization, and can be applied to platform development and actual engineering demonstration construction of virtual power plants, car network interaction and other platforms for excavation and improvement. The potential of system flexibility resources, improve the level of flexibility resources, and provide a copy -available experience in the promotion and application of virtual power plants across the country.

As an emerging business, the development of virtual power plants is inseparable from government support. In mid-June this year, the Shenzhen Municipal Development and Reform Commission issued the "Shenzhen Virtual Power Plant Plan (2022-2025)" to formulate a virtual power plant with a 1 million kilowatt-level capable capacity in 2025, forming the annual maximum load of about 5%of the stable response capabilities of stable response capacity The overall goal of putting forward more than 10 key guarantee measures is proposed to maximize the adjustment potential of Shenzhen distributed resources to build a new type of power system with high efficiency interaction of source network loads, helping Shenzhen to complete the "dual carbon" goal with the first demonstration standards Essence

"Under the circumstances of unclear policies and unclear market mechanisms, relevant enterprises are willing to invest in construction and access in advance. The Shenzhen Power Supply Bureau will form a priority access enterprise after covering the principles of covering various types of resources and regulating excellent control capabilities. "The relevant person in charge of the Shenzhen Power Supply Bureau of Southern Power Grid said that under the guidance of the market mechanism, it is expected that a large number of load aggregates will take the initiative to apply for access. At the same time, the bureau will also develop a universal virtual power plant based on security chips and independent domestic software running control terminals to solve the problem of large -scale distributed user -side resource safety, efficient and low -cost access problems. Future market income is considerable

The reporter learned that virtual power plants are a new type of intelligent control technology and interactive business model. The biggest feature of virtual power plants is to aggregate to cope with various situations. The virtual power plant can be used as a "positive power plant" to supply the system to the system, and it can also be used as a "negative power plant" to increase the load disappearance and system reclamation. It can quickly respond to instructions to cooperate with the stability of the guarantee system and obtain economic compensation. It can also be equivalent to the participation of power plants to obtain economic revenue from various power markets such as capacity, power, and auxiliary services.

In fact, the construction of a virtual power plant has also been included in the national plan. In late March this year, the National Development and Reform Commission and the National Energy Administration issued the "Fourteenth Five -Year Plan" modern energy system plan, which clearly proposed to carry out industrial adjustable load, building air -conditioning load, big data center load, user side energy storage, new energy sources, new energy sources Various virtual power plant demonstrations such as automobiles and power grids (V2G) energy interaction, while promoting flexible resources such as energy storage facilities, virtual power plants, and users to interrupt loads to participate in power auxiliary services.

"In the early days of the development of virtual power plants, the market mechanism is not yet perfect. It will fully mobilize and stimulate the enthusiasm of users to participate in virtual power plants through scientific and technological projects, and cultivate users of virtual power plants." "With the gradual improvement and landing of the market mechanism, virtual power plants will be able to participate in various markets such as the power energy market and auxiliary service market. Gradually form a sustainable development path of fairness, reasonable, free competition. "

In order to achieve the goal of "connecting virtual power plants with a load of more than 1 million watts in 2025", the Shenzhen Power Supply Bureau of the Southern Power Grid will explore and improve the standard standard system of virtual power plants and establish a virtual power plant elastic resource library. By comprehensively arranging various types of adjustable resources and market entities such as users who have more emphasis on energy -saving, load aggregates, industrial parks and other market entities to form a dynamic response resource library of virtual power plants. At the same time, it expands market transaction varieties and actively studys the price mechanism and trading rules of virtual power plants participating in green power transactions, distributed power generation transactions, and carbon -benefit markets.
