This paper demonstrates the effectiveness of Demand Side Response (DSR) with renewable integration by solving stochastic optimal operation problem (OOP) in IEEE 118-bus distribution system over 24 h. An Improved Walrus Optimization Algorithm (I-WaOA) is proposed to minimize costs, reduce voltage deviations, and enhance stability under uncertain loads, generation, pricing. The I-WaOA utilizes three strategies: fitness-distance balance method, quasi-opposite-based learning, Cauchy mutation. optimally locates sizes photovoltaic (PV) ratings wind turbine (WT) capacities determines power factor WT DSR.
