On November 13, the first district-level Virtual Power Plant (VPP) Operations Center in Changzhou was inaugurated at the New Power Equipment Innovation Park in Changzhou Economic Development Zone. The center was jointly established by State Grid Changzhou Power Supply Company and the Changzhou Economic Development Zone Administrative Committee.

As of date, the VPP operations platform has connected data from 69 users, including six park-based resources, eight industrial enterprises, 53 charging or energy stations, and two commercial buildings. With an aggregated capacity of 79.2 MW, the platform provides strong support for the market-based operation of load-side resources and the stable functioning of the regional power system.

The project was launched in March this year, and on July 22, the VPP operations platform began trial operation. The platform adopts a three-tier architecture: The first tier is the VPP and microgrid centralized control platform, which connects upward to the Changzhou municipal VPP monitoring and management platform and downward to various resource nodes. Through aggregation and coordinated control, it participates in demand response, ancillary services, and electricity market transactions. The second and third tiers consist of the micro-grid layer and the micro-grid resource layer, focusing primarily on the operation and maintenance of different types of micro-grids.

As one of Changzhou's first near-zero-carbon park pilots, the Songjian Lake Photovoltaic Tech Port micro-grid went into operation last month and has now been successfully connected to the VPP Operations Platform. The site features the city's longest photovoltaic corridor, with a total installed capacity of 6.168 MW, along with a 7.5-MW energy storage station.

The micro-grid's adjustable capacity, response speed, and other key indicators are monitored in real time, while it also receives load-control instructions to flexibly dispatch storage and solar output during peak electricity demand. According to estimates, the Songjian Lake Photovoltaic Tech Port is expected to reduce its basic electricity charges by 150,000 yuan in November, lowering the cost of electricity by about 0.3 yuan per kWh—achieving truly "optimized economic operation."
