“…Other studies [11,[52][53][54] propose approaches in the economic dispatch using multi-period OPF due to specific challenges to the traditional OPF such as the modeling of charge/discharge of ESS, or a specific ESS technology featuring [55]. Other studies have included more variables in order to bring the problem closer to a more precise context such as [56,57] using power losses constraints on the transmission branches to evaluate different generation scenarios.…”

“…The inherent features of this type of resources as uncertainty and variability impact power system operation [7][8][9][10]. In this context, power systems require strategies to integrate such intermittent resources with flexibility to meet the demand requirements [11]. The energy storage systems (ESS) represent a technology to store renewable energy according to their availability during the day (i.e., there are high quantities of electricity from PV systems at noon).…”

The power system operation considering energy storage systems (ESS) and renewable power represents a challenge. In a 24-hour economic dispatch, the generation resources are dispatched to meet demand requirements considering network restrictions. The uncertainty and unpredictability associated with renewable resources and storage systems represents challenges for power system operation due to operational and economical restrictions. This paper develops a detailed formulation to model energy storage systems (ESS) and renewable sources for power system operation considering 24-hour period. The model is formulated and evaluated 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 under different operational circumstances. With regard to the systems proposed, there are scenarios in order to evaluate ESS performance. In one of them, the increase in capacity did not represent significant savings or performance for the system, while in the other it was quite the opposite especially during peak load periods.

“…Owing to the intermittency and volatility of RE, microgrids with DGs can not only lead to the problem of dumped energy but also affect the stability of power supplies [3,4]. The application of ESS can stabilise the output power fluctuation of microgrid and improve the power quality [5][6][7][8][9]. It is thus important to determine the optimal capacity of DGs and ESS for the economic and reliable operation of isolated microgrid.…”

Microgrid systems, such as solar photovoltaic (PV) and wind turbine (WT), integrated with diesel generator can provide adequate energy to supply increased demands and are economically feasible for current and future use considering depletion of conventional sources. It is, thus, important to determine the appropriate sizes of PV, WT, diesel generator, and associated energy storage system (ESS) for efficient, economic, and reliable operation of electric power system in microgrid. Stochastic nature of intermittent renewable energy (RE) resources complicate their planning, integration, and operation of electric power system. Therefore, it is critical to generate typical scenarios of wind speed, irradiation, and load time series to reflect their stochastic characteristic for microgrid system planning and operation. In this study, a wind-irradiation-load typical scenarios generation method is proposed for optimal sizing RE resources of microgrid. The teaching-learning-based optimisation (TLBO) method is used to find the best configuration of the microgrid system. Simulation results show that scenarios generated by the proposed model have ability to approximate the original scenarios and reduce planning data effectively.
