Abstract
The provided is a reactive power optimization method for a power system based on distributed interval optimization, including following steps: S. constructing a first model, where the first model includes an interval reactive power optimization model of a power system with a high renewable energy penetration rate, and the interval reactive power optimization model includes an objective function, a first constraint, and a constraint of an interval power flow equation; S. obtaining a first state variable interval based on the constraint of interval power flow equation and a distributed interval power flow algorithm; S. Converting the first model based on the first state variable interval and a security limit definition method, and obtaining a second model, where the second model includes a deterministic optimization model; and S. obtaining a voltage and reactive power control strategy based on the second model and a primal-dual interior point method.
