Summary:
With the penetration of renewable energy sources to reduce the emissions of carbon-emitting technologies, there has been an increased interest towards using batteries to improve system reliability. However, batteries have a limited lifespan due to the degradation process that occurs during the charge and discharge cycles, resulting in a decrement in their energy storage capacity. Most of the batteries’ operating costs are related to this process, making these costs necessary to be included in the economic dispatches. This paper proposes a new mathematical model that formulates and solves an economic dispatch problem considering the battery's charge and discharge cycles as output variables. The model considers an endogenous representation of the ageing cost and, therefore, impacts other model variables. A series of case studies for the MIBEL system has been carried out, analyzing the effect of considering the ageing cost versus not considering it.
Spanish layman's summary:
En este artículo se muestra un nuevo problema de programación matemático lineal para optimizar la operación de baterías eléctricas a medio plazo, representando los costes de degradación. El modelo representa los ciclos de carga y descarga como decisiones del despacho económico de mínimo coste.
English layman's summary:
A new linear mathematical model to optimize the operation of storage technologies for the medium term, including degradation costs, has been developed in this paper. The model represents charge and discharge cycles as variables in the cost minimum economic dispatch.
