Battery Uses for Regulating Active Power in Utility-scale Wind-based Hybrid Power Plant

Growing demands for renewable energy sources have resulted in the integration of wind and solar power in utility-scale power plants and the building of a hybrid power plant. This requires a deep understanding of the interactions between the different technologies. To overcome the inherent intermittency of these sources, batteries are often used as energy storage. However, the proper utilization of batteries in these hybrid power plants remains a challenge because of the dynamic nature of renewable energy sources. Additional research is required to investigate how different dynamic technologies interact and perform dispatch energy as a single convenient unit. This research provides a battery contribution control approach for utility-scale wind-solar hybrid power systems. The proposed control strategy incorporates a supervisory control framework with a focus on establishing oversight of active power and enhanced interaction with different technologies involving the battery’s state of charge. Using MATLAB simulations and dynamic modelling, the effectiveness of the suggested control approach is tested. The results indicate that the control technique improves battery use, and minimizes wind and solar power curtailment to fulfill the power demand. This research offers a promising solution for the battery contribution in utility-scale wind-solar-battery hybrid power plants thereby contributing to grid stability and the integration of renewable energy sources.
