Reliability Evaluation of Roy Billinton Test System

Reliability play's a major role at power system planning and operation. Reliability means continuous power supply to end users without outages. So in order to study reliability of any system we consider two methods which are Analytical and Monte-Carlo simulation. Analytical methods are mathematical models which gives numerical calculations for simple systems. Monte Carlo Simulation is a proposed method which is used in case of complex systems. RBTS BUS-2 test system is used as case study with DG’s at different locations and without DG’s to evaluate fundamental reliability indices, customer oriented indices SAIFI, SAIDI, CAIDI .Cost/worth indices such as EENS, ECOST and IEAR are calculated and compared by both Analytical and Monte-Carlo simulation. In Monte-Carlo time sequential technics indices are calculated by using random number generators with UP and DOWN states times of system elements.
