Community Microgrid Wind Power Integration: Intelligent Coordination of Distributed Generation and Local Power Grid

Community Microgrid Wind Power Integration: Intelligent Coordination of Distributed Generation and Local Power Grid

Integrating wind power into community microgrids effectively utilizes local clean energy, but the intermittency and volatility of wind power pose challenges to the stable operation of the local microgrid. The key to achieving this integration lies in establishing intelligent coordination and control between the distributed wind power generation system and the community microgrid.

The core of intelligent coordination is "prediction, smoothing, and balancing." The system first needs to make short-term forecasts of wind power output within the community and, combined with the community's overall electricity load curve, formulate power generation and consumption plans in advance. Since wind speed variations can cause fluctuations in wind power output, the microgrid needs to use energy storage devices (such as batteries) or cooperate with other controllable power sources (such as gas generators) to smooth out wind power fluctuations and minimize their impact on the grid. More importantly, the intelligent control system needs to monitor the microgrid's voltage and frequency in real time. When a large amount of wind power is suddenly connected or disconnected, it quickly adjusts other power sources or controllable loads to ensure real-time balance between power supply and demand in the entire community grid, and that voltage and frequency remain stable within safe ranges.

This requires wind turbines to be grid-friendly and microgrids to have flexible control mechanisms. Modern grid-connected wind turbines can adjust their power output within a certain range according to grid requirements. Simultaneously, community microgrids can proactively manage non-critical electrical equipment (such as water heaters and charging stations), encouraging their use when wind power is abundant and temporarily suspending their operation when it is insufficient, thus flexibly absorbing wind power. All of this is automatically accomplished by a central energy management system, which acts like a brain, coordinating wind turbines, energy storage, other power sources, and various loads to achieve optimal operation.

Through this intelligent coordination and control, community microgrids can not only safely and efficiently connect to wind power but also maximize the proportion of local clean energy consumption, reduce dependence on the external grid and electricity costs, and enhance the community's power supply resilience during external grid failures. It is a crucial component in building a smart, green, and resilient community energy system.
