Probabilistic estimation of capacity value of photovoltaic system

Popular alternatives of conventional sources are wind and solar. Still power system planners are uncertain in estimating the contribution made by the intermittent sources. Authors have made some effort to find out the available capacity of PV system depending on the global solar radiation intensity and the load met by the effective capacity. Load met by the PV system is termed as effective load carrying capability (ELCC), is estimated by comparing reliability indices loss of load expectation (LOLE) before and after adding PV system. A test system is considered to validate the proposed methodology.
