Solution

System Expansion/ Peak Shifting

The system is to regulate users' power consumption curves through charging and discharging processes of the energy storage battery to realize transferring power of low power price in valley period to high power price in peak period for utilization. Peak-valley price difference and lowered basic capacity fee can realize arbitrage and reduce configuration capacity and load loss of users' power distribution and voltage transformation from users' value perspective.

Micro-grid

Micro-grid and main commercial grid undergo grid-connected operation under the circumstance that they are normal. The capacity generated by the micro-grid is prioritized to meet utilization requirement of local users' loads. It dispatches with the main commercial grid in case of remaining or insufficient electric quantity. The micro-grid will actively disconnect from the main commercial grid and operate independently to guarantee normal operation of main loads in case its system detects fault of the main grid and serious issue of power quality.
