How can distributed PV and Internet+ be better integrated, and how can Internet + better promote the rapid development of distributed PV and the implementation of PV subsidies?
Since the National Grid Corporation held a "State Grid Distributed Photovoltaic Cloud Network Conference" in Beijing in April this year, the company has issued a number of policies to actively promote the sustainable and healthy development of the photovoltaic industry. The "13th Five-Year Plan" clearly requires that the installed capacity of distributed photovoltaic power generation in the country should exceed 60 million kilowatts in 2020, and further strengthen the integration of distributed photovoltaics and the cloud platforms such as the Internet.
State Grid Corporation has been developing new energy sources such as highly distributed photovoltaic power generation as a major strategic measure and important political responsibility, social responsibility and economic responsibility for implementing the national energy strategy, service strategy emerging industries, and promoting the transformation of economic development mode. Distributed power supply is safe and healthy. In order to fully implement the requirements of the "Guiding Opinions on Promoting the Development of "Internet +" Smart Energy", State Grid Corporation has continuously increased the depth and breadth of the integration of the Internet and its main business, with the State Grid Mall (PC side) and e-po Based on the (mobile side), the State Grid distributed photovoltaic cloud network was built, and an open and shared distributed photovoltaic energy Internet ecosystem was constructed through the “Internet + Photovoltaic†approach.
Focusing on solving the pain points and difficulties of the distributed photovoltaic industry, the PV cloud network launched four major features:
(1) One-stop service, PV cloud platform provides users with one-stop service and overall solution, including online filing application with online characteristics and on-grid progress inquiry, to achieve online and offline business.
(2) Real-time monitoring, the PV cloud platform can realize on-line inquiry and monitoring of daily and monthly on-grid electricity tariffs and equipment operating conditions.
(3) Subsidy advance payment, State Grid E-commerce Company advanced the photovoltaic subsidy by introducing financial products, effectively solving the painful point of government PV subsidy funding.
(4) Financial services, photovoltaic cloud platform docking a large number of financial institutions (banks, trusts, insurance, etc.), providing customers with distributed photovoltaic income rights pledge, factoring, on-grid electricity financing, property insurance and other financial services, and effectively solve customer shortages And financing difficulties and other issues.
Cloud connectivity solution for distributed photovoltaicsWM6232/WM2232 is a wireless inverter wireless data acquisition module of ZLG Zhiyuan Electronics for distributed photovoltaic industry. The module collects and records the working state and power generation of the inverter to monitor the photovoltaic power generation system for a long time. Transfer data to the service platform via Wi-Fi/GPRS so that users can query anytime, anywhere. The series products not only support standard communication modes such as transparent transmission, but also provide users with a wealth of software function interfaces. Users can quickly define individual functions such as inverter interaction protocol according to their own product requirements, which is very suitable for distributed photovoltaics, etc. Wireless networking monitoring of the device.
Wi-Fi module is specially designed for the application environment of single-family villas. It adopts dual antenna design. The matching of antennas has been strictly tested and verified. The signal quality is optimized to effectively enhance the strength and penetrating power of the signal. More than 100m, the ability to adapt to different environments has also been significantly improved, effectively reducing the signal dead angle!
The Wi-Fi module not only supports the common AP and StaTIon working modes, but also supports the AP&StaTIon modes. The module can also be used as a hotspot to connect other devices while accessing the router. For example, it can be convenient for mobile phones while working. Ipad, notebook and other access for wireless configuration.
The module supports the simultaneous establishment of four TCP links, enabling multiple management centers to simultaneously manage and monitor one device.
This series of products is based on the ZLG Zhiyuan AWorks platform software architecture design, integrated with a stable wireless communication protocol, and a full range of products using a unified API interface, users can quickly develop secondary based on their own applications. Whether using Wi-Fi, GPRS or future LoRa, NB-IoT products, users only need to implement one application to apply to all products in the series.
In the communication process, not only the stable transmission of data needs to be considered, but also good, no chaos, no loss, and security and confidentiality of user data are required. The module adopts DES/3DES data encryption specification to ensure user data security.
The interactive protocol of the PV inverter needs to be upgraded and updated in time when necessary. The acquisition module not only supports remote upgrade itself, but also upgrades and maintains the program of the inverter through the acquisition module, which greatly improves the maintainability of the product.
Distributed PV inverter products may be installed outdoors due to limited space during installation. Therefore, this series of module enclosures are designed with IP65 waterproof design (after module installation), which can be used in outdoor environments to avoid rain, dust and The scorching sun caused damage to the communication module.
For distributed photovoltaic systems (roof photovoltaic systems), we have specially improved and optimized the antenna of the Wi-Fi/GPRS module, and integrated the market-proven wireless protocol driver, focusing on the widespread Wi- in the industry. The Fi/GPRS connection has intermittent or connected but no data problems, which greatly reduces the operation and maintenance cost. In terms of signal enhancement, the Wi-Fi module has a line-of-sight communication distance of more than 100m, covering most of the Villa type.
A modern gel battery (also known as a gel cell) is a VRLA battery with a gelified electrolyte; the sulfuric acid is mixed with fumed silica, which makes the resulting mass gel like and immobile. Unlike a flooded wet cell lead-acid battery, these batteries do not need to be kept upright.
