摘要：
For optimal operation of wind-power-integrated multi-area interconnected power systems, this paper proposes a security-constrained coordinated decentralized dispatch approach taking multiple uncertainties (including forecast error of wind power and load, generator fault and tie-line tripping) and mutual reserve support into consideration. Firstly, the probabilistic output of wind farm considering forced outage of wind turbine is modeled. Then, by modifying the capacity outage probability table (COPT), the reserve demand based on reliability level is obtained. Next, a security-constrained coordinated decentralized dispatch model is established, integrated stochastic-robust optimization is adopted to address multiple uncertainties and a two-level analytical target cascading algorithm is designed to realize coordinated decentralized scheduling of tie-line power and mutual reserve. Through exampleanalysis oftwo-area 78-bus system and two-area 236-bus system, validity of the proposed approach and economy of the interconnected mutual reserve mode are verified. © 2019, Power System Technology Press.
