As the brain of integrated energy service, smart energy management, based on IoT and cloud technologies, provides multi-dimensional services including multi-functional panoramic monitoring, refined energy efficiency management, multi-energy collaborative and optimal control, intelligent operation and maintenance, virtual power plant and carbon asset management, so as to ensure the energy use is “visible”, “manageable” and “saved”, and help enterprises, campuses, hospitals, airports, buildings, industrial parks and other users to improve their energy management and achieve the goals of reliable energy supply, fine energy use and energy efficiency.

01.Multi-energy full-dimensional perception

By deploying local intelligent acquisition and control terminals for cooling, heating, electricity, gas, water, etc., the plug-and-play real-time acquisition of multi-energy system is realized, thus fulfilling the informatization and intelligent management of multi-energy system and providing data support to constructing the refined energy management.

02 Refined energy-efficiency management

Through various business functions such as meter reading, energy balance chart, energy Kanban, energy use statistics, cost analysis, multi-dimensional bench-marking analysis, and energy use prediction, we can timely find weak points in the energy-use process, provide accurate analytical reports, achieve energy conservation, consumption and emission reduction, and improve the quality of energy management.

03 Optimal energy efficiency and closed-loop control

It terminates the status quo of monitoring without controlling in most smart energy management. Through the horizontal multi-energy coordinated and optimal control of “cooling, heating, electricity, gas and water”, and the vertical “source grid load storage” coordinated optimal scheduling, it realizes the multi-energy coordinated optimal control, fully taps the energy-saving potential, achieves energy-efficiency and consumption reduction, reduces carbon emissions, boosts the achievement of the dual-carbon goal, and achieves both economic and social benefits.

1) Support horizontal and vertical indicator analysis with multiple ranges and dimensions to identify abnormal energy consumption.

2) Considering the system operation, formulate and optimize control energy-saving plan and energy use strategy.

3) Based on data changes on monitoring platform, track how the energy-efficiency plan is executed.

04 Situation early warning and awareness

Through the situation early warning and awareness technology, it makes early-warning perception and analysis of the current and future operation situation of the enterprise’s integrated energy system and other users, identifies intelligently the abnormal measurement in advance and other abnormal working conditions, carries out the intelligent alarm push prompt, so as not to affect the production while improving the stability of the integrated energy system.

05 Intelligent operation and maintenance management

It conducts remote monitoring and centralized operation and maintenance management of many scattered photovoltaic, energy storage, distribution rooms, water pump rooms, etc. Through remote centralized real-time monitoring, worksheet management, operation and maintenance plan management, fine intelligent analysis, etc., it realizes the regulated operation and maintenance management while reducing the operation and maintenance cost.
