Power system operation considering detailed modelling of energy storage systems

Abstract

The power system operation considering energy storage systems (ESS) and renew-able power represents a challenge. In a 24-hour economic dispatch, the generationresources are dispatched to meet demand requirements considering network restric-tions. The uncertainty and unpredictability associated with renewable resources andstorage systems represents challenges for power system operation due to operationaland economical restrictions. This paper developed a detailed formulation to modelenergy storage systems (ESS) and renewable sources for power system operation in aDCOPF approach considering a 24-hour period. The model is formulated and evalu-ated with two different power systems (i.e. 5-bus and IEEE modified 24-bus systems).Wind availability patterns and scenarios are used to assess the ESS performance un-der different operational circumstances. With regard to the systems proposed, thereare scenarios in order to evaluate ESS performance. In one of them, the increase incapacity did not represent significant savings or performance for the system, while inthe other it was quite the opposite especially during peak load periods
