To enhance the utilization of renewable energy and the economic efficiency of energy system's planning and operation, this study proposes a hybrid optimization configuration method for battery/pumped hydro energy storage considering battery-lifespan attenuation in the regionally integrated energy system (RIES).
Therefore, if the battery operates without considering lifespan attenuation, the cost of replacing the battery beyond the project period must be considered, thereby resulting in a considerably high overall system cost.
In terms of power distribution strategy and energy management, Hou et al. proposed an energy management method which can reduce the load fluctuation of battery by combining online parameter identification and adaptive model predictive control, and improve the efficiency and reliability of the system .
A novel approach was also introduced in for the optimal configuration of battery energy storage systems (BESS) in power networks with a high penetration ratio of a PV station. To achieve tangible results, the daily fluctuations in node demand, generation scheduling, and solar irradiance were considered.
In order to improve battery life, the hybrid power supply composed of lithium-ion battery, ultra-capacitor, and DC/DC converter has become one of the research hotspots of energy storage technology [ 2]. The use of ultra-capacitors can improve the system efficiency and the braking energy recovery efficiency of the vehicle.
The degradation of battery performance and capacity seriously restricts the power capacity of the battery. The range, life span and safety of battery systems have become the technical bottleneck restricting the development of electric vehicles.
