　　Virtual power plant energy IoT system

　　In essence, the virtual power plant is to use the energy Internet technology to integrate thousands of enterprises' micro grid distributed controllable loads, charging piles, distributed photovoltaic, distributed energy storage, etc. into a certain scale, adjustable load resources and power generation capacity. Through this invisible "power plant" to coordinate with the demand response of the large grid, solve the problem of large peak valley difference in the grid, local power supply tension and other problems while making profits, which is a win-win situation for the power grid and power consumption enterprises. Since the beginning of this year, virtual power plants have received frequent policy support and have sparked a development trend in the industry. The main reason is that the contradiction between peak and valley electricity in China is becoming increasingly prominent. In the future, virtual power plants can play a key role in alleviating the supply-demand contradiction, improving the stability and flexibility of the power grid.

　　Virtual power plants have a relatively mature operating mechanism abroad, but at present, there are few projects that have truly landed in China's virtual power plants, and most of them are pilot projects. As Mr. Yu Qing said, on the one hand, virtual power plants cannot sustain profitability at present; On the other hand, the infrastructure of virtual power plants, which consists of numerous enterprise microgrids, has a low degree of digitization. Therefore, a significant amount of resources need to be invested in the early stages to achieve the digitization of enterprise microgrids. The low-level digitization of enterprise microgrids has become one of the biggest constraints on the development of virtual power plants.

　　The cloud platform is a set of platforms based on the Ankeri IoT data center, which has established the uplink and downlink data standards and provides Internet users with energy IoT data services. Users only need to purchase Ankerui IoT sensors and transformers, and install them themselves. Whether it is IoT instrument direct transmission or uploading through the gateway, they can use their mobile phones to scan the code to obtain the required industry data services.

　　system architectureThe Acrel EIoT energy IoT cloud platform adopts a layered and distributed structure, mainly composed of three parts: the perception layer (terminal collection devices), the network layer (communication management terminals), and the platform layer (energy IoT cloud platform).

　　Perception layer: Various sensors connected to the network, including multifunctional meters, prepaid meters, multi loop meters, IoT meters, IoT water meters, electric vehicle charging stations, car charging stations, street light controllers, etc. Network layer: Intelligent gateway, collects data from the perception layer, performs protocol conversion and storage, and uploads the data to the energy IoT cloud platform. Platform layer: includes application servers and data servers, which can implement applications on PC or mobile devices.

　　How to establish a digital enterprise microgrid

　　The energy management awareness of enterprises determines the level of digitalization of their power grids. Experts predict that there will be further policies (such as demand response, energy dual control, carbon emission constraints) and price incentive mechanisms to promote the establishment of microgrid digitalization in enterprises, and to build infrastructure for the promotion and development of virtual power plants. At the same time, it will also enhance the energy management awareness of enterprises and generate value for them through digital energy management. How can companies establish microgrid digitalization that is suitable for themselves?

　　The digital system (EMS) for enterprise microgrids includes sensors, intelligent gateways, and microgrid digital software installed on-site. Sensors are used to monitor and control the load equipment and distributed generation equipment (systems) inside the enterprise. The data of field sensors are accessed to edge computing intelligent gateways. Each intelligent gateway can be regarded as a regional headquarters. After collecting the data of the received sensors for protocol conversion, it is uploaded to the EMS and forwarded to the third-party system. The gateway can perform logical calculation and execute EMS instructions according to preset thresholds or automatic learning. EMS can be seen as the command center of enterprise microgrids, generating various charts, control strategies, and analysis conclusions based on data uploaded by intelligent gateways, and responding to scheduling instructions of virtual power plants according to set permissions. This large number of EMS forms the foundation of virtual power plants
