Battery Energy Storage System

What is energy storage? Energy storage mainly includes the storage of thermal energy, kinetic energy, electrical energy, electromagnetic energy, chemical energy and other energy.Electric energy storage is an important part of the six major links in the electric power production process: "collection-generation-transmission-distribution-use-storage". Electric energy storage methods include: battery type energy storage, inductor type energy storage, capacitor type energy storage and other types of energy storage.

Battery Energy Storage System (BESS) is a system that uses lithium batteries/lead batteries as energy storage carriers to store electrical energy for a certain period of time and supply electrical energy for a certain period of time. The energy storage system is in the power generation link. This is undoubtedly a great boon for new energy power generation systems that abandon wind and light. The discarded electric energy is stored and released when needed to provide electricity for areas without electricity, and for those with electricity. Establish micro-grids in regions to promote new energy. For the transmission, transmission, distribution, and use of the entire power system, the energy storage system can play important roles in energy transfer, peak and frequency modulation, peak shaving and valley filling, and power backup. It provides a full guarantee for building an informatized, automated, and interactive smart grid. All in all, the energy storage system is like a reservoir in a drought, like a Passport for new energy.

The key components of the energy storage system are mainly divided into four parts: energy storage carrier battery, battery management system (BMS), energy storage converter (PCS), and energy management system (EMS). Among them, the main function of the battery management system (BMS) is to monitor and protect the battery cells, mainly to improve the utilization rate of the battery and prevent the battery from overcharging and over-discharging. It can be used for electric vehicles, battery cars, robots, and drones. Wait. As the interface between the grid and the energy storage device, the energy storage converter (PCS) is also an important part of the energy storage system. It can be applied to grid-connected energy storage systems, island operation of energy storage systems, and state switching between the two. EMS energy management system is the general name of modern power grid dispatching automation system (including hardware and software). Its main function is composed of two parts: basic function and application function. Basic functions include: computer, operating system and EMS support system. Application functions include: data acquisition and monitoring (SCADA), automatic power generation control (AGC) and planning, network application analysis. The current mainstream energy storage research and development directions are the development of energy storage converters, the design of energy storage monitoring and protection systems (control strategies, functions, system frameworks), and battery energy storage design and application research.

Recently, RWE Renewables, a subsidiary of RWE Group, an overseas German energy developer, is building a solar farm with an installed capacity of 195.5MW in Georgia, USA, and is deploying a 40MW/80MWh battery energy storage system. In China, battery energy storage is in an important position and vigorously develops new infrastructure.

Now that there is a battery energy storage system, how do you know the power and other related information such as current and voltage etc? At this time, many people will choose to use DC meters to meet wide current & wide voltage measurement. EM613001 and EM613002 are specially created for this application scenario. At the same time, they can also be widely used for metering of charging pile. Two models are attached.
