In recent years, with the increasing global attention to environmental protection and climate change issues, the new energy industry has developed rapidly. According PFSK151 to the International Renewable Energy Agency (IRENA), global renewable energy capacity additions are expected to surge to 440 GW in 2023, an increase of 107 GW year-on-year, which is the largest increase in new
capacity ever recorded. Solar photovoltaics will account for two-thirds of the growth in renewable power generation this year.
However, photovoltaic power generation is limited by weather conditions and solar radiation intensity, sunshine duration, cloud cover and other factors under different geographical locations, and the power generation is difficult to predict. The energy storage system can store the excess energy of photovoltaic power generation and release it in the case of insufficient photovoltaic power generation or power failure, effectively improving the reliability of photovoltaic power supply. In order to promote the development and application of energy storage technology, the Chinese government has increased policy support, and the energy storage market is also expanding, and there will be broader application prospects in the future. Zhaoyue Communications followed suit and took advantage of the trend to actively develop PFSK151 and promote photovoltaic energy storage solutions, aiming to contribute to the
development of green energy.Photovoltaic energy storage system composition
Photovoltaic energy storage system is mainly composed of battery packs, battery management system (BMS), monitoring system (SCADA), energy management system (EMS), communication system and so on.
1. Battery pack: the core of the energy storage system, a power supply composed of multiple battery packs in series for charging, discharging and storage of electric PFSK151 energy.
2. Battery management system (BMS) : responsible for monitoring the status of the battery pack, charge and discharge control of the battery, real-time collection of the operating data of the battery pack, monitoring and control of battery voltage, current, temperature and other parameters, and maintenance and PFSK151 management of
the battery according to the status of the battery.
3. Monitoring System (SCADA) : responsible for real-time monitoring and management of the operating status of the energy storage system. SCADA can collect the operating data of the energy storage system in real time, and send the data to relevant personnel for monitoring and management through the
communication system to ensure the safe and stable operation of the energy storage system.
4. Energy Management system (EMS) : responsible for the energy management of the entire energy storage system, able to monitor, control and optimize the operation of the energy system, including energy scheduling, energy monitoring, fault diagnosis, energy analysis, etc., to provide efficient and stable energy management for energy storage facilities.
5. Communication system: responsible for the real-time transmission of data between different devices in each subsystem of the energy storage system. It can realize the functions of remote monitoring, intelligent control, information interaction and security protection of the entire system, improve the PFSK151 operation efficiency and safety of the energy storage system, and provide a strong guarantee for the stable operation of the
energy storage system.
System topology
Communication system Overview:
In the energy storage system, communication equipment plays a crucial role. Reasonable selection and configuration of communication equipment can ensure the stable operation and efficient management of the energy storage system. Among them, the photovoltaic ring network and
the energy storage ring network adopt the MR-ring redundant ring network composed of Shanghai Zhaoyue industrial Ethernet switch MIE-2412A, and the self-healing time is less than 20ms, which can effectively prevent the network paralysis caused by a node failure. The main switch adopts the Cronet CC-3452, a three-layer 10-gigabit high-throughput industrial Ethernet switch, which can support a maximum of 48 10/100/1000M electrical ports and 8 10-gigabit SFP+ expansion slots. The interfaces are rich and flexible, and gigabit or 10-gigabit bandwidth can be selected according to the size of the energy storage project, making the system more compatible. Greatly facilitate the future system upgrade and expansion. At the load end, Shanghai Zhaoyue's new MWG-3611 series 5G+WIFI6 wall-mounted industrial wireless router can be used, which supports 1 10/100/1000M adaptive WAN port and 4 10/100/1000M adaptive LAN ports. The monitoring operation center can realize remote monitoring, cloud data management, fault troubleshooting and other functions through MWG-3611, and 5G+WIFI6 can meet the needs of clients for high-speed, efficient, and high coverage, with
greater bandwidth, faster transmission speed, lower latency, and higher PFSK151 reliability.
Program features:
All industrial switches and 5G routers are designed with low power consumption, and Cronet CC-3452 is used as the main switch. The 10-gigabit network not only ensures the transmission bandwidth, but also facilitates the future upgrade and expansion of the system.
2.5G+WIFI6 industrial routers can support more devices to connect to wireless networks at the same time, thereby increasing network speed.
3. Support MR-ring protocol, self-healing time <20ms, effectively prevent network paralysis caused by single point of failure, ensure the high reliability of the system operation.
4. Powerful network management functions, supporting VLAN, MQTT access protocol, port management, priority setting, broadcast storm suppression and other functions.
5. Comply with international standards, support IEC61850 protocol, support SNMP v1/v2 public management protocol.
6. Wide temperature design, support -40℃ ~ +75℃ working, industrial level 4 electromagnetic compatibility design, suitable for use in extremely harsh PFSK151 environment.
