SimSES Multi-Use: A simulation tool for multiple storage system applications

The rapidly falling capital expenditures and rising energy and power densities of battery energy storage systems are leading to more widespread use of these systems in both mobile and stationary applications. In stationary applications, it is expected that the economic potential of a battery energy storage system will improve when serving multiple applications simultaneously. In this work, the newly developed tool, SimSES Multi-Use, is introduced, which is capable of simulating an energy storage system that serves multiple applications simultaneously. Furthermore, the techno-economic impact of multi-use operation strategies on the energy storage system is explored. In its present state, the tool allows the modelling of several applications, depending on the scenario explored. Available applications include: frequency containment reserve, peak shaving, self-consumption, and compensation of reactive power. In line with other publications, simulations conducted in this work confirm, that the stacking of applications is more lucrative than single-use operation. Both economic and technical characteristics of the battery are considered in this work.
