Details of the Microgrid Intelligent PV-Storage Coordinated Project
The Microgrid Intelligent PV-Storage Coordinated Project integrates photovoltaic, energy storage, and intelligent control technologies to achieve efficient energy dispatch and stable grid support. The key details are as follows:
- System Architecture and Components: The project typically includes distributed PV (e.g., rooftop or carport PV), energy storage battery systems (e.g., liquid-cooled or containerized energy storage), and charging facilities. For example, one case adopted a 200kW rooftop PV system paired with a 100kW/200kWh containerized energy storage system, which uses an intelligent strategy server (e.g., CET-7320) to coordinate equipment operation, achieving integrated management of source, grid, load, and storage. The platform supports real-time monitoring of PV generation, energy storage charge/discharge status, and charging pile data, ensuring local consumption of electricity and reducing reliance on the grid 45.
- Core Operating Strategies:
- Self-Consumption Strategy: PV prioritizes meeting local loads. Surplus electricity is not directly fed into the grid but is instead allocated for energy storage charging or shifted to adjustable loads. When PV output is insufficient, energy storage discharges to supplement. This strategy, combined with peak-valley electricity pricing mechanisms, enables two charge-discharge cycles, reducing user electricity costs by 15%-30% 4.
- Anti-Reverse Power Flow Control: Mandatory energy storage allocation (e.g., 10%-20% capacity) is used to smooth PV intermittency. Through local distribution cabinets and intelligent algorithms, surplus electricity is prohibited from being fed into the grid, reducing PV curtailment and increasing the self-consumption rate by 40%. For example, in a machinery factory project, this strategy addresses changes in solar irradiance and load fluctuations, enhancing system stability by 15% 25. In the field of transportation integration, the highway solution demonstrates the extended application of PV-storage-direct-flexible microgrids, providing a dynamic video demonstration.
- Intelligent Management Functions: Based on Model Predictive Control (MPC) and an IoT platform, dynamic dispatch optimization is achieved. The system automatically responds to grid frequency fluctuations (response time ≤20ms) and supports seamless switching to off-grid mode (delay <500ms), ensuring power supply to critical loads. The O&M platform features energy efficiency analysis, safety warnings (e.g., overcharge/overdischarge protection), and remote strategy configuration, improving energy utilization efficiency and achieving the annual carbon reduction target of thousands of tons 45.
Application Benefits
- Economic Efficiency Improvement: Through peak-valley arbitrage and ancillary service revenue, the payback period for energy storage investment is shortened, and the levelized cost of electricity (LCOE) for PV-storage synergy is reduced, with typical projects showing significant annual revenue growth 2.
- Scenario Adaptability: Applicable to industrial parks, highway service areas, and microgrid scenarios, supporting multi-source coordination (e.g., PV + diesel generators), achieving flexible energy interaction and carbon reduction targets 45.
