“…The ELCC is calculated by first computing the system's LOLPs without as (1) where the probability function accounts for the likelihood of generator or other failures and stochastic loads or renewable resource availability. The base system's LOLE is defined as (2) Generator is added to the system and a fixed load, , is added to each period, giving a new LOLE…”

We present a method to estimate the capacity value of storage. Our method uses a dynamic program to model the effect of power system outages on the operation and state of charge of storage in subsequent periods. We combine the optimized dispatch from the dynamic program with estimated system loss of load probabilities to compute a probability distribution for the state of charge of storage in each period. This probability distribution can be used as a forced outage rate for storage in standard reliability-based capacity value estimation methods. Our proposed method has the advantage over existing approximations that it explicitly captures the effect of system shortage events on the state of charge of storage in subsequent periods. We also use a numerical case study, based on five utility systems in the U.S., to demonstrate our technique and compare it to existing approximation methods.

“…Even more recently, the California Public Utilities Commission opened a rulemaking process to set policy for California utilities and load-serving entities to procure energy storage systems. 1 The assigned commissioner's ruling lists capacity among the benefits that storage can provide.…”
