Therefore, as the application space for ESSs grows, energy storage valuation is of a particular interest of many energy storage stake holders (e.g., ESS owners, system operators, regulators, and researchers). If there is a net positive benefit that meets the return on investment criteria, no further analysis is required. For other applications, e.g., energy arbitrage in a market, valuation analysis can provide a revenue estimate for a given storage system and a benefit/cost analysis can be easily performed. After this analysis yields a size and location, additional analysis must be performed to compare the cost of potential alternatives. For services that provide a technical benefit, e.g., raising the frequency nadir after the loss of a large generator, dynamic simulations are required to properly size and place the energy storage system. While all deployment decisions ultimately come down to some sort of benefit to cost analysis, different tools and algorithms are used to size and place energy storage in the grid depending on the application and storage operating characteristics (e.g., round-trip efficiency, life cycle). A summary of energy storage applications is given in Table 1. This results in three categories: behind-the-meter (BTM) applications, front-of-the-meter (FTM) applications (e.g., market areas), and operation in a vertically integrated utility. Another approach for categorizing storage services is by the governing rate tariff or market rules.

For example, a storage system is acting as a generator while discharging when it is providing a transmission or distribution deferral benefit. It is not uncommon for a storage system to provide a benefit to more than one category. Another method for classifying storage applications is assigning the benefit to generation, transmission, or distribution. Examples of energy applications include energy arbitrage and renewable energy time shift. Examples of power applications include frequency regulation, synthetic inertia, and small signal stability. Power applications transpire over short periods of time, milliseconds to seconds, and are often associated with real-time control of the power grid. High-power low-energy cycles are referred to as power applications while long-duration discharges are referred to as energy applications. A common method is based on the time scale of the charge/discharge cycle. There are several ways to categorize these services. Energy storage systems (ESSs), with the ability to alternatively charge and discharge energy, can provide a wide range of grid services to tackle the above challenges.
Furthermore, there are challenges in mitigating the impacts of natural disasters and protecting grid infrastructure against cyber/physical threats. A major concern is the high variability and uncertainty of these resources and loads. A review of analysis tools for evaluating the technical impacts of energy storage deployments is also provided, as well as a discussion of development trends for valuation and design tools.Īs the electric grid evolves very quickly toward more renewable and distributed energy resources integrated with controllable loads, grid operators have experienced many technical problems in maintaining grid stability and reliability.

While many of the tools, developed by the national laboratories, are free to use, the commercial tools are also of great importance in meeting the customers’ specific needs. These tools can be classified into two groups: (1) power system simulation and planning tools for analyzing the technical contributions of ESSs, and (2) techno-economic analysis tools for valuating the economic benefits of ESS deployment and specifying the optimal design of energy systems that include ESSs. There are many software tools for valuating ESS. Since there are many analytical tools in this space, this paper provides a review of these tools to help the audience find the proper tools for their energy storage analyses. As the application space for energy storage systems (ESS) grows, it is crucial to valuate the technical and economic benefits of ESS deployments.
