Optimal Power Dispatch in Combined Heat and Power Systems with Solar and Wind Integration

Cogeneration, or combined heat and power (CHP) generation system delivers electrical energy and recovers dissipated heat, reducing costs, emissions, and enhancing renewable energy integration by smoothing intermittency. CHP economic dispatch problem (CHPED) is necessary for handling load dynamics and addressing the uncertainty of nonconventional energy sources. The primary focus of this proposed work is to minimize overall operational expenses while adhering to generator constraints and giving priority to solar, wind power output. For solving this CHPED problem, an arithmetic optimization algorithm (AOA) is utilized to obtain an optimal solution. In this study, a 10 -unit framework is tested to establish the effectiveness of CHPED both including and excluding solar and wind power. Obtained results shows significant decrease of $18 \%$ in operational costs by incorporating considered renewable energy sources. This approach can enhance the integration of wind and solar source energy generated power as distributed sustainable energy into the CHPED process.
