This study focuses on the control strategy for active power management in utility-scale co-located hybrid power plants (HPPs) comprising wind, solar, and battery storage system. With the increasing importance of environmental impacts and incentives for renewable energy, hybrid power plants have become an attractive option for plant developers. However, there is a lack of research on the control strategies and framework of these HPPs, particularly at the utility-scale when multiple sub-technologies are involved. The proposed control strategy incorporates a supervisory control framework with a focus on establishing oversight of active power among hybrid power plants and enhanced interaction with different technologies. Using MATLAB simulations and a dynamic model, the performance of the suggested control is tested under different operational and weather conditions. The proposed control strategy for active power management can contribute to bridging the gap in knowledge and improving the controllability and efficiency of utility-scale co-located HPPs.
