Sino-Singapore Tianjin Eco-City Household PV Achieves "Plug and Play"

Recently, the smart household photovoltaic project in the smart grid innovation demonstration zone of the Sino-Singapore Tianjin Eco-city was launched, and 10 demonstration households realized the "plug and play"
of photovoltaic power generation for self-use and grid connection by installing photovoltaic power generation integration facilities led by the State Grid Tianjin Electric Power Company.

In the demonstration family of Jiaming Hongshuwan Community of Sino-Singapore Tianjin Eco-City, the integrated PV/energy storage device can automatically realize the optimal distribution of energy according to the photovoltaic power generation, load consumption power and grid status, improve the self-consumption rate of photovoltaic power generation, improve the reliability of power supply for important loads, reduce the impact on the power grid, and realize the plug-and-play function
.
The home energy router is connected to the home controllable load through the customer's internal smart socket, which can collaboratively control distributed photovoltaic, energy storage and controllable load, and realize the energy circulation
between the three.
Customers can also use the mobile client to view the working status information of the equipment in real time, grasp the household electricity consumption and grid-connected electricity data, and realize the optimal management
of household energy efficiency and electricity bills.

Smart home construction is an important part
of the Sino-Singapore Tianjin Eco-City Smart Grid Innovation Demonstration Zone.
For a long time, State Grid Tianjin Electric Power Company has been committed to building a clean, efficient, friendly and interactive smart grid, relying on the "Sino-Singapore Tianjin Eco-City Smart Grid Innovation Demonstration Zone Project" and "Key Technology Research and Demonstration Application of Household Photovoltaic Power Generation System" and other national and State Grid Corporation science and technology projects, innovated and practiced the organizational construction mode of "multi-party joint construction and win-win cooperation", and led the independent research and development of household photovoltaic plug-and-play devices
。 In the State Grid Corporation of China, it cooperates with China Electric Power Research Institute, Nari Group Co.
, Ltd.
, Xuji Group Co.
, Ltd.
and other institutions to form an organizational team, and signed a strategic cooperation agreement
with the intelligent electricity industry alliance externally.
At the same time, State Grid Tianjin Electric Power actively reported to government departments, signed strategic cooperation agreements with local governments, and sought policy support to jointly build a smart electricity business model to achieve win-win
cooperation.
On this basis, State Grid Tianjin Electric Power innovates and expands the intelligent power service model, relies on the smart grid to develop home energy efficiency management, carries out home energy efficiency analysis and diagnosis, and provides system services
such as smart power consumption, smart home, user management, terminal management and equipment management.
On the one hand, more detailed electricity consumption data on the residential side can be obtained to provide a data basis for grid load forecasting.
On the other hand, residents can keep abreast of the operation status of the power grid, obtain power consumption notices and electricity price policies, set and adjust electricity consumption behaviors according to electricity consumption notices, realize the response of residents' electricity demand, and improve the efficiency of electric energy utilization and grid operation
.

It is understood that the distributed photovoltaic power generation integrated facilities installed in the demonstration households of the Sino-Singapore Tianjin Eco-City include core components
such as 3 kW photovoltaic power generation devices and one integrated device.
State Grid Tianjin Electric Power actively communicates with the Sino-Singapore Tianjin Eco-City Management Committee, residential properties, customers and relevant parties to promote the plug-and-play technology and model
of distributed power supply through demonstration and application of plug-and-play integrated devices.
In addition, by interacting with the smart home network, customers can use the mobile phone client to view the working status information of the device in real time, grasp the data of household electricity consumption and grid-connected electricity, and realize the optimal management
of home energy efficiency and electricity bills.

State Grid Tianjin Electric Power personnel said that distributed photovoltaic power generation to achieve "plug and play", which is of great significance for large-scale distributed power friendly access and the construction of community energy networks, providing strong support
for building a smart public service network, building an urban energy Internet, and promoting the implementation of the global energy Internet strategy.
