In the context of severe environmental problems, renewable energy development and power system reform, smart energy, energy internet and other technologies have emerged as the times require. Integrated energy projects have developed rapidly with technological upgrading, especially integrated energy projects based on multi-energy complementation that are represented by smart parks. After the outbreak of the COVID-19 pandemic, the industrial parks of major enterprises were shut down and production was suspended. In the future, the normal energy supply and energy production management of parks need to be intelligentized.

Multi-energy complementation in parks is an important part of smart parks. Commonly seen multi-energy complementation systems in parks include distributed power source, large power grid, distributed electrochemical energy storage, charging equipment, etc. CYG SUNRI’s overall solution of multi-energy complementation and integrated energy efficiency for parks can provide integrated project services, realize coordinated supply by energy systems in parks, improve energy utilization efficiency, improve power supply reliability, and reduce customers' expenditure on electric energy. The company also develops a smart energy efficiency management system (EEMS) for users. The system can be operated and monitored in real time by several persons simultaneously, and centralized work on site is not required. The system meets users’ requirements of remote operation and maintenance, effectively reduce close contact and improve the intelligent management.

About the Solution

In this project, the BAPV power generation system, the energy storage system, the DC lighting and the electric vehicle fast charging devices in the regional power material warehouse are combined to form a system integrating PV power generation, energy storage and charging. The system can drive the loads with PV, power grid and energy storage. Multiple types of energy complement each other, and power is supplied in a coordinated manner. The system enables the normal power supply and use of the park in grid-connected and off-grid modes, and improves the cost performance of power use and the reliability of power supply in the park.

Innovation in the Project

The standardized design of regional power material warehouse based on BIPV is proposed, so as to connect multiple types of distributed PV power sources to the regional warehouse, and promote the green development of the regional warehouse;

The technology for integrating PV power generation, energy storage equipment and logistics EV charging station in the power regional warehouse is developed to improve the utilization efficiency of urban land;

The DC microgrid power supply technology is applied to the regional warehouse to optimize the energy use mode;

The integrated monitoring of the park is proposed for the real-time monitoring of various energy sources and energy use. The park becomes more intelligentized.

The smart energy EEMS can collect the data of power generation, energy storage and load in the whole system, and control the power balance and voltage stability of the power grid in the park through smart dispatching algorithm, thus optimizing the energy use mode of the park. In addition, water, electricity, gas, heat and air conditioning systems can be connected to the park. Integrated energy management can be realized to improve energy saving and reduce power consumption in the park.
