Decentralized Stochastic Control of Power Systems Using
نویسندگان
چکیده
A decentralized feedback control scheme is proposed for optimization of large-scale systems. First, local controllers are used to optimize each subsystem, ignoring the interconnections. Next, an additional compensating controller was applied to minimize the effect of interactions and improve the performance of the overall system. At the cost of the suboptimal performance, this optimization strategy ensures stability of the system. To account for the modeling uncertainties, both a local Kalman filter and a novel approach by the usage of genetic algorithm is used to estimate all local states and interactions for each subsystem. A sample three-bus system is given to illustrate the proposed methodologies.
