Techno-economic analysis of integrating battery energy storage systems in industrial buildings

A techno-economic model is provided in this research to assess the viability of using building-integrated battery energy storage systems (BI-BESS) in industries. The factor of beta as the ratio of energy to power is introduced in both economic and technical calculations to quantify the economic feasibility of the project with the help of a simple iterative algorithm for battery sizing. The load profile from an industrial building in Malaysia is considered for checking the effectiveness of the results. In addition, the optimum size of the battery achieved by comparing the optimum beta from the benefit-cost ratio against beta graph, and the increment E against beta graph. The results show that the optimum battery sizing achieved 84.05 kWh at beta = 1.6. Furthermore, the battery parameters that affect the feasibility of using BI-BESS are evaluated. Finally, the results show that the proposed method is independent of the building load profile, and the same graph will apply to all buildings using the industrial tariff and current BESS technology for checking the feasibility of projects.
