Reliability and Active Power Loss Assessment Of Power System Network With Wind Energy

This paper presents wind energy as a possible alternative to the present conventional generation systems. Multi turbine wind systems situated in various farms are analyzed by incorporating the number of turbines, their repair and failure rates and, their forced outages. The impact of wind upon reliability indices and its effect on power flow are the main objectives of this paper. Discrete Markov Chains and Monte-Carlo simulations support the model to calculate Capacity Outages and Probability. Loss of Load Expectations (LOLE), Expected Energy Not Supplied (EENS) and Expected Demand Not Supplied (EDNS) indices are calculated for reliability assessment and comparison between the original and modified system. Load Flow analysis for daily estimation of active power losses reflects the reduced line losses when wind energy is incorporated in the system. The IEEE RTS-79 system of 24 bus is examined here, for evaluation of reliability indices.
