Summary: In recent decades, renewable energy sources, such as wind power, have significantly increased their presence in the global energy mix, playing a crucial role in reducing fossil fuel usage and environmental hazards, especially in remote areas where diesel power plants were the main source of energy. However, hybrid power systems face challenges like frequency deviations. This paper presents a methodology to tune diesel engine governors using the Student Psychology-Based Algorithm, improving controller performance metrics and providing better system response, as demonstrated in the simulation of a wind-diesel power system on San Cristobal Island, Ecuador.

Summary: The load disturbance rejection ability of electrical machine systems is crucial in many applications. Existing studies mainly focus on improving disturbance observers, but the speed response control during the transient also plays a significant role. This paper proposes a sliding mode disturbance observer-based load disturbance rejection control with an adaptive filter and a Smith predictor-based speed filter delay compensator to enhance the transient speed response.

Summary: In power system scheduling with variable renewable energy sources, considering both spatial and temporal correlations is a challenging task due to the complex intertwining of spatiotemporal characteristics and computational complexity caused by high dimensionality. This paper proposes a novel probabilistic spatiotemporal scenario generation (PSTSG) method that generates probabilistic scenarios accounting for spatial and temporal correlations simultaneously. The method incorporates Latin hypercube sampling, copula-importance sampling theory, and probability-based scenario reduction technique to efficiently capture the spatial and temporal correlation in the dynamic optimal power flow problem. Numerical simulations demonstrate the superiority of the proposed approach in terms of computational efficiency and accuracy compared to existing methods.
