Performance analysis of wind–hydro power plant under multi-state failures and repairs.

Hybrid power plant system is an excellent option for providing electricity for remote and rural locations where access of grid is not feasible or economical. In this paper, a renewable energy-based system which is a combination of wind and hydro power plant is considered to produce electricity. Where, wind power plant has a provision of single rotor and two generators to produce electricity and hydro power plant works as a standby. Some differential equations have been derived with the help of Markov process and solved by Laplace transformation. Reliability, availability, cost benefits and sensitivity analysis of wind–hydro power plant (WHPP) have been derived and illustrate with the help of their graphs. The purpose of this work is to supply significant amount of reliable and renewable energy by combined WHPP and evaluate the reliability characteristics of WHPP. Combining, wind with the hydropower is one way to make the grid more reliable. [ABSTRACT FROM AUTHOR]
