In this paper, an active voltage regulation strategy of the partitioned stator switched flux permanent magnet (PM) (PS-SFPM) generator is proposed to enable the PS-SFPM generator supplying isolated passive load to obtain a stable output voltage at different load conditions. The target is achieved through mechanically varying the relative inner stator position and adjusting the PM flux-linkage. Over...
With increasing integrations of large-scale systems based on permanent magnet synchronous generator wind turbine generators (PMSG-WTGs), the overall inertial response of a power system will tend to deteriorate as a result of the decoupling of rotor speed and grid frequency through the power converter as well as the scheduled retirement of conventional synchronous generators. Thus, PMSG-WTGs can provide...
This paper proposes a multi-objective optimization method for solving the Security-Constrained Optimal Power Flow (SCOPF) problem with the consideration of solar farm integrated and distributed load variations in the grid. In this scheme, the power generated by solar farm is affected by the weather uncertainty. The dispatch objectives are formulated to minimize fuel cost and emission simultaneously...
This paper proposes a probabilistic model for optimal joint allocation of energy and spinning reserve to determine energy and spinning reserve capacities. The model takes into consideration both the hourly changes of load demands and the probability of generators' contingencies. The objective function aims at minimizing not only fuel costs caused by power generation but also the costs associated with...
