Bulk Power Systems Reliability Assessment with Wind Farms in Electricity Market Environment

With the energy crisis and the strengthening of the human consciousness on environmental protection, the usage of new energy sources for power generation has attracted wide attention, in which wind power with low-cost and mature technology become relatively faster growth among new energy power generation technology. Because wind energy has the characteristics of random and intermittent, which may affect power systems reliability, it is necessary to assess power systems reliability containing wind farm. Unlike sensitivity method and weighting factor method calculating load loss, the optimal scheduling model is proposed in this paper, which could embody the difference of load and fault duration. The case study results show that the different types of grid-connected wind farms could influence bulk power systems reliability, which should be paid more attentions under actual situation.
