摘要

With rising electricity costs, increasing environmental awareness and aggravating legal requirements, production plants demand innovations in the field of energy efficiency and utilization of renewable energies. Here we perform a techno-economical assessment of photovoltaic-battery storage systems for industrial peak-shaving and self-consumption applications. In order to consider individual load profiles, different battery types, aging mechanisms, varying costs for electricity and storage capacity, a simulation tool was developed. Net present value method was applied to evaluate the costs over the systems’ service life. The case study shows positive net present values for system configurations with large photovoltaic systems compared to storage capacity.
