3、 Platform functions

1. Microgrid management function

• Peak shaving and valley filling: combined with energy storage equipment, low charging and high discharging to optimize energy consumption costs

• Ordered charging: Guided by transformer capacity and electricity prices, utilizing technology to coordinate charging power and reduce operating costs

• Anti reverse flow: For self use new energy systems, prevent the reverse transmission of power to the grid, and avoid assessments and fines

• Demand control: energy storage, charge and discharge power tracking to prevent an increase in basic electricity bills

• Demand response: Based on incentives and electricity price demand response, user participation is driven by economic benefits.

• Flexible expansion: When the short-term power consumption exceeds the transformer capacity, the energy storage can be quickly discharged to meet the energy requirements of the load

2. Aggregation, optimization and regulation of virtual power plant resources

By aggregating photovoltaic, energy storage, charging piles, and air conditioning flexible loads within the microgrid, functions such as resource overview, resource management, resource aggregation, collaborative control, and response evaluation are constructed to provide resource aggregation, market transactions, and friendly collaborative interactive business support.

3. Power monitoring and energy management

By installing various intelligent sensors such as monitoring, metering, control, and protection on key locations and equipment in power supply and distribution, a complete power measurement, metering, and control system covering 35kV to 0.4kV is built. Combined with video surveillance methods, 24-hour uninterrupted monitoring of internal electrical energy in enterprises and institutions is achieved. Instantly identify potential hazards in power supply and distribution, reducing the frequency of accidents. Instantly locate the fault point and shorten the recovery time.

4. Power quality monitoring and governance

Power quality analysis supports monitoring of Class A devices, obtaining real-time steady-state (three-phase imbalance, voltage frequency deviation, etc.), transient (voltage rise/fall/interruption), transient data, and harmonic spectra. It can record SOE events, perform high-precision waveform analysis, annotate transient intervals through ITIC/SEMI F47 curves, and generate diagnostic reports in accordance with national standards to determine the qualification of indicators; In terms of governance, SVG is used to alleviate voltage fluctuations and flicker, APF is used to control load side harmonics, and the power factor controller automatically switches capacitors. At the same time, the operation status of the governance device is monitored, and timely alarms are issued in case of faults.

5. Electrical safety

Electrical contact temperature measurement requires the installation of temperature measuring devices at cable joints and other connection points to sense temperature in real time and send alarm information in a timely manner; In addition, the end circuits of places such as electric vehicle charging should be equipped with electrical fire-resistant current limiting protectors. When the circuit is short circuited, it can quickly limit the current within 150 μ s to avoid electrical fires; Lighting and socket safety monitoring can control neutral line overcurrent caused by 3N harmonics and three-phase imbalance, support independent setting of overcurrent feedback values, and have functions such as uploading power quality data, automatic neutral line overcurrent disconnection, and platform data monitoring.

6. Intelligent lighting

The intelligent lighting control system can achieve intelligent operation control of lighting equipment, effectively improve the scientific management level of lighting systems, and save operating costs. By using timed switches and dimmable technology, ineffective lighting can be effectively avoided, allowing for accurate utilization of each lighting power source. This is an effective means of achieving green lighting, energy conservation, and emission reduction.

7. Air conditioning control

The central air conditioning system consists of a cold and heat source system and an air conditioning system (end air system). Under the same objective environment, the number of start stop devices and the setting of air temperature and speed determine the overall power consumption of the system; Load regulation can be achieved through AI optimization of central air conditioning, which combines AI algorithms to predict cooling/heating loads in real time, adjust the operating parameters of the host, water pump, and cooling tower fans, and combine rigid and flexible control strategies to improve system efficiency, reduce electrical load, and avoid over demand.
