Radial feeder reliability evaluation in the presence of battery storage using modified Sequential Monte Carlo simulation

Smart Grid initiative requires improvements to distribution system operation. One of the improvements is to use battery storage to support the distribution system. These batteries have the ability to improve the system reliability. This work develops a simulation based reliability evaluation technique with detailed battery operation model. The state of charge of battery, loss of capacity over age and the limited battery capacity are used in the battery operation model. To incorporate the effect of one element on the failure of a component downstream to it modified Time Sequential Monte Carlo (TSMC) is proposed in this work. The first part of this work proposes the modified TSMC and tests its usability using a feeder from Roy Billinton Test System (RBTS) and the results are compared with the analytical and Time Sequential Monte Carlo Technique. The second part of the work evaluates the reliability indices of a simple feeder in the presence of battery storage.
