This paper presents an improved levellized cost of storage (ILCOS) index for comparing various storage technologies. The ILCOS is a modified index based on the conventional levellized cost of storage (LCOS) that includes the effect of daily self‐discharge. This index calculates the total cost of discharged energy for a storage system over its lifetime. Comparing the conventional LCOS and the proposed ILCOS metrics indicates that the ILCOS is a more accurate index for the economic analysis of storage technologies. Also, this paper introduces an algorithm by using the ILCOS index for selecting the optimum storage technology in any individual application. The algorithm inputs are the needed discharge time, the required stand‐by time, and the technical and economical characteristics of storage systems; the output is the optimum storage technology. Based on the discharge time, this algorithm investigates the storage technology in three categories: short‐duration, medium‐duration, and long‐duration applications. Any storage system that has the minimum ILCOS is the economically winning technology. Given the characteristics of the existing storage technologies, the case study shows that for long‐duration applications, the pumped hydroelectric storage (PHS) is the best option. Also, vanadium redox flow battery (VRFB) and lead‐acid (PbA) batteries are the most economic storages for medium‐duration applications.

“…The formulation process of the operation strategy of the pumping and storage power station is as follows: the planners of the dispatching organization of each province arrange the operation curve of the pumping and storage power station according to the load of the province, that is, the pumping plan, which is submitted to the dispatching organization of the large region for review and implementation. However, there are some problems in the operation strategy of energy storage resources [4] .…”

Modern energy system presents the trend of "scenery leading and multi-source coordination". Accepting more fluctuating power supplies and loads with different characteristics puts forward higher requirements for the flexibility of the system, and the role of energy storage resources in the operation of the system is becoming more and more important. At present, the understanding of energy storage power stations is mostly limited to peak shaving and valley filling, easing the tension between power supply and demand and so on. In the future, the value of energy storage will be more reflected in realizing the dynamic balance between power supply and demand, smoothing output fluctuation and load change, improving the consumption of renewable energy, providing auxiliary services in the power market, so as to improve the safety, economy and flexibility of power grid operation and realize the coordinated and optimal operation of energy storage and modern power system.

The hydrogen-electric integrated energy station will play an important role in the new power system with renewable energy as the main body. This paper establishes an optimization model for the system configuration of a hydrogen-electricity integrated energy station, further explores the differences in optimal configuration and operation modes of different station construction modes with different basic conditions in different places, and discusses the reasons. The research shows that the economy of the grid-connected mode is the best, and the economy of the off-grid mode is the worst. The local electricity price policy, wind and solar resource endowment, and stability will significantly impact the integrated energy station. At the same time, in the regions where the wind and solar resources fluctuate greatly from month to month, hydrogen can play the role of long-term energy storage.
