Hybrid Compensation Strategy for Coordinated Reactive Power Management in Multi-Energy Systems

In modern power system, the efficient reactive power dispatch is very much crucial for maintaining the overall reliability of the system. This paper presents a novel approach for coordinated reactive power optimization in multi-energy system with a hybrid compensation strategy. The proposed approach utilizes a combination of superconducting magnetic energy storage (SMES) and shunt capacitor banks to dynamically balance reactive power demands across varying generation profiles and load conditions. A comprehensive objective function is formulated to minimize power losses as well as reactive power injections to upgrade voltage profiles. The Cultural Algorithm framework provides a robust mechanism to explore and exploit the complex search space associated with these nonlinear power system optimization problems. The modified IU-62 bus test system is used for simulation to prove the effectiveness of the proposed hybrid approach. Results show significant improvements in reactive power allocation and voltage stability compared to base values. The findings suggest that Cultural Algorithm-based approach hold better strategies for the applications involving hybrid energy storage and compensation technologies.
