Industrial and commercial energy storage is the current distributed energy storage system in the user side of the typical application scenario, its characteristics are close to the distributed photovoltaic power supply end and load center, not only can improve the absorption rate of clean energy, but also effectively reduce the transmission loss of power, the current main application scenarios include peak and valley arbitrage, demand (capacity) management, emergency power backup, dynamic capacity increase and demand side response.
An energy storage power station is a power station set up to regulate peak and valley power consumption. It converts renewable energy sources (such as solar, wind, etc.) into electricity and stores it to supply power during periods of peak demand or power system failures. The core function of energy storage power station is to balance the contradiction between supply and demand in the power system and improve the stability and reliability of the power system.

Comparison of industrial and commercial energy storage and energy storage power station system configuration

01 Battery

Industrial and commercial energy storage has relatively low response time requirements, considering cost and cycle life, response time and other factors.

The income of energy storage power station mainly comes from power auxiliary services, so the energy storage battery system of frequency modulation power station has high requirements on cycle life and response time.

02 Battery Management System (BMS)

Industrial and commercial energy storage battery system can provide over-charge, over-discharge, over-current, over-temperature, under-temperature, short circuit and current limiting protection functions for the battery pack. Voltage balancing function is provided during charging, parameter configuration and data monitoring can be carried out through background software, and the energy storage system can be intelligently managed.

The energy storage power station manages the single battery, battery pack and battery stack by layers, levels and unified management, calculates and analyzes the various parameters and operating status of the battery according to the characteristics of each layer and level, and realizes effective management such as balance, alarm and protection, so that each battery can achieve equal output and ensure the best operating state and longest running time of the system. Provide accurate and effective battery management information, battery balance management can greatly improve battery energy utilization efficiency and optimize load characteristics. At the same time, it can maximize the battery life and ensure the stability, safety and reliability of the energy storage system.

03 Energy Storage Converter (PCS)

The function of industrial and commercial energy storage inverter is based on bidirectional converter, small size, easier to integrate with the battery system; Can be flexibly expanded according to their own needs; With a wide voltage range of 150-750V, it can meet the series parallel needs of lead-acid batteries, lithium batteries, LEP and other batteries; Unidirectional charge and discharge, suitable for various types of photovoltaic inverters.

The DC side voltage of the energy storage power station is wider, and 1500V can be fully loaded. In addition to the basic functions of the converter, it is also necessary to have the functions of power grid support, such as primary frequency modulation, fast scheduling of source network load, etc., and the power grid has strong adaptability and can achieve fast power response (<30ms).

04 Energy Management System (EMS)
EMS system for industrial and commercial energy storage is mainly for local energy management. The EMS system, which has won the national invention patent, supports the balanced management of the battery of the energy storage system for industrial and commercial energy storage scenarios, ensures the safety of operation, supports the millisecond fast response, and realizes the integrated management and centralized regulation of the energy storage subsystem equipment.
Energy storage power stations have high requirements for EMS systems. In addition to basic energy management functions, they also need to provide grid scheduling interface and energy management functions for microgrid systems. It needs to support a variety of communication protocols, has a standard power dispatching interface, and can manage and monitor the energy of applications such as energy transfer, microgrid, and power frequency modulation, and monitor multi-energy complementary systems such as source network, load and storage.
