Active power output calculation of wind farms connected to power grids based on fuzzy chanceconstrained programming

Based on the fuzzy random chance-constrained programming(FRC)theory, the paper presents a method to calculate active power output of large-scale wind farms connected to power grid. The calculation of calculate active power output can be turned into a FRC programming problem which constrained conditions. This paper put forward a mathematical model of calculate active power in wind power integrated system based on FRC programming form. These include ramp constrains of the generating units, output restricted zone, line transmission capacity, reserved capacity constraints, the balance of load, and so on. The question is solved by particle swarm optimization based fuzzy simulations. The results on IEEE30 system demonstrate the advantages of the proposed approach.
