The "14th Five-Year Plan" proposes that accelerating the digital and intelligent upgrading of the energy industry is a supporting way to achieve the "double carbon" goal, and the energy consumption of smart parks, as the most concentrated space for urban carbon emissions, has rich business types and diverse business models, which is an important foothold for the implementation of energy digitalization and low-carbon transformation.
At present, a considerable scale of various large and medium-sized science and technology parks and industrial parks have been built in China, but the energy supply and use of most parks are still in a relatively extensive state, which cannot meet the needs of improving the overall intelligent level of the park.
On the one handThe existing park lacks intelligent energy system operation control technology and energy management methods, which is difficult to effectively meet the large-scale access of distributed power sources, distributed energy storage devices, electric vehicles and the demand-side response of usersOn the other handMost of the energy supply equipment systems in the existing park are built independently according to their respective specialties, which cannot meet the requirements of comprehensive energy efficiency management in the park.
The specific performance is as follows:
The office electrical equipment of the enterprise exceeds the actual line load, and the power is too large, causing overload tripping and power outage
Abnormal power lines and equipment, resulting in short circuit and overload tripping of the line;Leakage leads to tripping;
Some enterprises wiring privately, resulting in high line load, high temperature of line and circuit breaker terminals, and burning out circuit breakers
The outdoor street lights and auxiliary lighting in the park are always turned on when there is no demand, wasting electricity
Lights and air-conditioning equipment in public areas are still turned on when no one is there and there is no demand for electricity
Toilet exhaust fan, machine room air conditioner, at night, holidays or when the usage rate is low, appropriately reduce the opening operation;
Gyms, restaurants, leisure areas, halls and other public areas are operating at full capacity around the clock.
There are different types of smart parksThe needs of different emphasesThe specific performance is as follows:
1) Industrial parks
The industrial development zone itself has a low demand for informatization, but the energy consumption of the park in the park is very large, and the demand for energy management in the park is more urgentIn addition, the traditional manufacturing industry will gradually fade, and park managers need to select and eliminate enterprises with backward production capacity in the park.
2) Trade and Logistics Park
Trade and logistics parks pay more attention to obtaining business opportunities and providing services to customers, so they focus on the needs of the park and can provide them with services such as energy consumption big dataIn addition, due to the trend of the warehousing part of the logistics industry to move out, the energy management of the warehouse can not be the focus.
3) Creative Software Park
The creative industry park focuses on innovation and small parks, focusing on providing information services necessary for incubation and growth, as well as smart energy management and smart payment for the settled parks.
4) Science and Technology Pioneer Park

5) Software Information Park
The software information park has a strong demand for informatization, but its own informatization level is also very strong, and it is necessary to focus on promoting applications that are difficult to invest resources in the software park, such as virtual cloud services and green buildings.
In addition, each park has a relative uniformity in terms of energy consumption, fire safety, and operational efficiency requirements. In terms of energy consumption: digital management is required, energy consumption information is grasped, and the potential of energy saving and consumption reduction is explored. In terms of fire safety, it is necessary to have a detection and fault diagnosis mechanism to fundamentally ensure that all energy-using equipment is in a normal and stable operating state, and to ensure the property and personal safety of the park. In terms of operational efficiency, there is an urgent need to improve energy efficiency and maintenance personnel management.
