PV-Storage Integration and Virtual Power Plants Gain Momentum as Smart PV Applications Enter a New Phase

Recently, the Ministry of Industry and Information Technology, together with four other ministries, released a list of typical smart PV projects. CHINT New Energy's Haining Smart PV-Storage Integrated Demonstration Project was among those selected. The project integrates four key components: a 5.97MW PV power station, a 10MW/20MWh energy storage system, a smart energy management platform, and a virtual power plant, creating an integrated system that covers green power generation, intelligent energy management, and market-based electricity trading.

The project adopts a self-generation and self-consumption model, with surplus electricity fed into the grid. It also combines energy storage for peak shaving with virtual power plant participation in electricity markets. The PV station generates approximately 5.2 million kWh annually, with a self-consumption rate exceeding 95%, reducing carbon dioxide emissions by 8,275 tons per year. The energy storage system operates on two charge-discharge cycles per day to effectively reduce peak electricity demand. The smart energy management platform uses IoT technology to connect system equipment and AI algorithms to optimize real-time energy dispatch.

Industry experts note that the project represents an advanced level of technology and application in China's smart PV sector and provides a replicable model for similar projects nationwide. The integration of PV and energy storage with virtual power plants offers a practical solution for the low-carbon transformation of industrial parks and manufacturing bases, and is expected to support greener and smarter energy use across a wider range of industrial and commercial applications.

Meanwhile, several energy storage projects have recently made progress worldwide. Jinko Solar successfully delivered a 2.15MWh commercial and industrial energy storage project in Australia. China Energy Engineering signed a 235MW PV + 581MWh energy storage off-grid power station project in the DRC, while SKYWORTH PV's 300MW/600MWh energy storage power station project in Jinzhong Development Zone recently broke ground. These projects span Australia, Africa, and the Chinese market, reflecting the accelerating expansion of the global energy storage sector.
