“…Assuming that EVs parked all day maintain SoC on a certain level and do not participate in frequency regulation, their battery life is only calendar life, not affected by cycle life. Literature [8] reports that at SoC 0.8 (battery charge: 80%), battery life is about 5 years; thus, k , k t in Eq. (5) are set to meet the condition of 5-year battery life as explained in Section 5.…”

Electric vehicle (EV) will prevail in the near future and many EVs are expected to be parked all day or almost all day according to a survey in Japan. They can contribute as vehicle-to-grid (V2G) to primary frequency regulation in power systems. However, as lithium-ion battery or EV battery is still expensive, it is economically important to evaluate V2G frequency regulation cost. This paper proposes the evaluation method of the frequency regulation cost. The proposed method is based on the EV battery cost and longevity, which is shortened by performing the frequency regulation. The battery degradation consists of calendar aging and cycle aging, and an empirical model is used in this paper. Simulation results are shown using the proposed method under the various conditions such as state of charge (SoC) of the EV battery. Those results indicate a V2G control strategy to increase the cost-benefit of primary frequency regulation.

“…3 On the contrary, many studies deal with empirical models that can be applied to actual battery operation. [3][4][5][6][7][8] This paper uses an empirical model for lithium-ion batteries to consider actual EV operation. Battery life consists of calendar life (elapsed time) and cycle life (charge-discharge cycles).…”

The integration PV systems into grid, due to the intermittent characteristics, can have several impacts on the network functionalities such as the stability, the protection and introduces new management and planning challenges. Theses impacts are more complicated for an islanded grid or weak grid. A better knowledge of the induced constraints becomes necessary in order to determine the PV penetration level, to assess impacts of PV generation on distribution network and to assess technical and economic opportunities provided by PV generation. This paper presents analyses on the impacts of PV systems integration to the grid: variation of voltage and frequency, voltage unbalance, etc. Several solutions, based on intelligent control, protection and energy storage in order to reduce these impacts, to maximize the ancillary services contributed by PV systems and to maintain the grid stability are proposed.

“…Calendar and cycling age [72] are the two main factors that cause the degradation of battery. Four models are used to fit the state-of-health (here, the ratio of the current usable capacity to the initial or nominal capacity) of the battery [72]. In addition, the degradation of the battery is also caused by the cycling operation.…”

Sizing of a stand-alone microgrid considering electric power, cooling/heating, hydrogen loads and hydrogen storage degradation

Microgrids are small-scale power systems with local generation, storage systems and load demands, that can operate connected to the main grid or islanded. In such systems, optimal components sizing is necessary to make the system secure and reliable, while minimizing costs. In this paper, a stand-alone microgrid considering electric power, cooling/heating and hydrogen consumption is built. A unit commitment algorithm, formulated as a mixed integer linear programming problem, is used to determine the best operation strategy for the system. A genetic algorithm is used to search for the best size of each component. The influence of three factors (operation strategy, accuracy of load and renewable generation forecasts, and degradation of fuel cell, electrolyzer and battery) on sizing results is discussed. A 1-hour rolling horizon simulation is used to check the validity of the sizing results. A robust optimization method is also used to handle the uncertainties and evaluate their impact on results.
