Disclosed is a method for modeling a medium and long term
wind power output model optimally operating in a medium and long term in a power
system. By calculating the
wind power output of the power
system during daily peak time period, daily valley time period, and daily shoulder
load time period, and optimizing
wind power output data during the daily shoulder
load time period, the capacity substitute benefit of
wind power generation is rationally taken into account, the operation reliability level of the power
system is guaranteed, the bidirectional peak regulation characteristic of wind
power output is considered, the peak regulation balance of the power system is guaranteed, the benefits of
energy conservation and emission reduction of wind power resources are fully exerted, the highest
utilization rate of the
wind power generation capacity is guaranteed, the feature of low wind power schedulability is fully taken into account, the randomness and volatility of wind
power output are correctly simulated, the practical situation of a
simulation project optimally operating in a medium and long term in the power system is met, and the purpose of better calculating the randomness, the volatility, the regionalism and bidirectional peak regulation performance of
wind power generation and a correlation between same and loads is achieved.
