A novel model predictive control (MPC) scheme is developed for mitigating the effects of severe line-overload disturbances in electrical power systems. A piece-wise linear convex approximation of line losses is employed to model the effect of transmission line power flow on conductor temperatures. Control is achieved through a receding-horizon model predictive control (MPC) strategy which alleviates...
A major challenge in power system operation is the integration of renewable energy in-feed in large scale. Currently, the responsibility to cope with uncertainty in power injection is transferred to a central authority, i.e. the system operator, while renewable energy in-feed is supported via a tariff system. In this paper we propose market participation of wind farms in combination with a third-party...
The high penetration of non-dispatch-able, gridconnected wind power is bringing serious challenge to the frequency regulation of power systems because of the decoupling between the output power of doubly-fed induction generatorbased wind farms and the grid frequency. Therefore, this paper proposes a compensation strategy to help wind farms to support the system frequency response by using the energy...
With the increasing penetration of renewable resources in power systems, more operational flexibility is required to deal with the uncertainty of intermittent generation. In particular, fast acting regulation reserves are needed to maintain the load-generation balance. This paper focuses on evaluating the benefits of energy storage in providing regulation services for real-time operation. Among the...
