Abstract

The impact of the integrated operation of photovoltaic (PV) and energy storage system (ESS) units on the energy SCR and SSR within an industrial park were investigated. The load characteristics of industrial parks, unlike those of general commercial facilities, are highly heterogeneous owing to their diverse process operations, varying load profiles, daytime operation rates, and peak power demands. Consequently, even if industrial parks and general commercial facilities have identical PV installation capacities, the resulting SCR and SSR widely differ depending on the operational characteristics of the site. Therefore, establishing an effective DER operation strategy for RE100 implementation in industrial parks requires an analytical framework that reflects the real-time matching between PV generation and load profiles as well as the capability of the ESS to store and reuse surplus energy. On-site renewable generation was studied as an RE100 compliance measure. and the SCR and SSR were analyzed based on annual operational data from PV and ESS systems using the actual electricity consumption characteristics of an industrial park. The annual SCR and SSR were 85.16% and 27.09%, respectively, under the evaluated conditions.
