ABSTRACT: This paper presents an evolutionary stochastic production simulation to
solve the optimal spinning reserve configuration problem in power system with
wind integrated. Equivalent load curve is generated with considering the wind
power forecasting deviation and generation scheduling of hydropower plant in
different water periods. The equivalent load duration curve (ELDC), redrawn
from equivalent load curve is the core of stochastic production simulation
which focuses on random outage of generator and load fluctuation. The optimal
spinning reserve model is established around the reliability index Expected
Energy Not Served (ENNS). The optimal scheduling of spinning reserve is reached
while the cost of purchasing spinning reserve is equal to the outage loss. At
last, results of the optimal spinning reserve model tested in Hainan power grid
help reduce the costs of spinning reserve configuration.
