Future demand for prospective providers of control reserves

Abstract

Due to higher forecast errors, the increasing amount of renewable energy sources in the European power system causes changes in the demand for load-frequency control reserves (CR). Additionally, the increasing renewable generation replaces the operation of conventional power plants, which provide a major share of today's demand for CR. Thus, a higher demand for CR encounters a reduced provision. This study presents a method for analyzing this deviation between the conventional provision and the future demand for CR. This deviation can be understood as a future demand for prospective providers of CR, such as wind parks or battery storage systems. The presented method is further applied to a future scenario of the German power system. Subsequently, prospective providers are evaluated according to their technical suitability to guarantee a sufficient provision of CR. The results show a demand for new providers of CR until 2030, especially for primary and secondary control reserve.
