Abstract: The global imperative for ensuring sustainable development has heightened the significance of reducing greenhouse gas emissions within the building sector. Consequently, a critical exploration into the integration of clean electricity within buildings has become indispensable. Therefore, this study focuses on the urgent global concern of reducing greenhouse gas emissions in the building sector to achieve sustainable development. However, the optimization of power systems encounters new challenges due to the unpredictable charging behavior of electric vehicles, resulting in flexible demand side management. These challenges necessitate a reevaluation of existing mathematical approaches. To ensure the utilization of clean electricity, a novel and cost-effective power supply system is proposed, specifically tailored for commercial buildings with a focus on creating a comfortable environment in a shopping mall. Furthermore, an energy management strategy is suggested to optimize energy usage. The study takes into account two types of electric vehicles and develops separate models for each based on their unique stochastic behaviors. Additionally, the integration of retired electric vehicle batteries in commercial buildings is explored as a potential solution. To address the inherent complexity of the problem, a developed algorithm based on multi-group search optimization is proposed. This algorithm effectively handles the uncertainties associated with electric vehicles and employs a decomposition approach to provide an optimal solution. The results demonstrate significant reductions of 82.17% and 83.32% in the expected operating cost through the integration of photovoltaic energy alone or both photovoltaic and retired electric vehicle batteries in commercial buildings, respectively. This emphasizes the benefits of incorporating photovoltaic and retired electric vehicle batteries in commercial buildings. Furthermore, the robustness of the proposed method is validated through a comparative analysis with alternative approaches.
