“…Next, West Japan system is divided into three areas, and parameters expressing respective PV output are assumed as p = [p 1 , Under these conditions, three cases of TS preventive control-LB, RLB, RUB-are considered. On the other hand, "Worst-case error" pertains to the evaluation with worst-case p obtained in optimization by Equation (13). In all cases, c i = 1 is set in objective function.…”

This paper proposes a monitoring and control method for transient stability (TS). First, it is clarified that there may exist various critical patterns of uncertain power flows causing instability due to photovoltaic generations. Then, the use of critical clearing time (CCT) is suggested as a TS index, which can be computed by conventional TS analysis tools. A distribution factor (DF) for controlling CCT is investigated, referred to as CCT-DF in this paper. Then, three optimization problems using CCT-DF are formulated based on bilevel optimization to obtain reliable operation planning. The combined use of the optimizations guarantees the power system robust security under uncertainties. K E Y W O R D Scritical clearing time, photovoltaics, transient stability, uncertainty 8

“…The day-h and h-min orders are used for forecast and scheduling with regard to uncertainties of intermittent renewable generators. Dynamic economic load dispatch (DELD) 6 in the h-min order utilizes unit commitment data and forecast to schedule generator outputs and reserve capacity in real time up to a specified time ahead. The min-s order is in charge of control, particularly, LFC control.…”

This paper proposes a real-time generation regulation system named as "on-demand generation regulation control" system, which is suitable for small independent power grids with unstable renewable energy generators. It has been developed as a part of "robust demand and supply control manager" and plays an important role of flexible frequency control that includes vehicle to grid and generation restriction when necessary. The main feature of the system is the integrated framework to effectively deal with hard-to-predict control options in a flexible way by observing the unstable generator outputs and all generators/batteries status including electric vehicles. In addition, a feedback system is also proposed to flexibly adjust the regulation capacity in case unexpected disturbances occur. The performance of the proposed system is verified through numerical simulations based on an actual test site with successful results.
