“…The UC model was developed in our preceding study and designed to optimize the hourly unit commitment plan for a generator via mixed integer programming in an attempt at minimization of the daily operation cost based on the power demand and PVS output forecast value for the next day . It should be noted that in the UC model of Ref.…”

“…It should be noted that in the UC model of Ref. , the fuel cost for a thermal power generator was approximated by a linear function concerning the output, while in this paper in pursuit of a more realistic computation, it was approximated by a quadratic function based on the fuel cost used in the power system standard model for the extended system developed by IEEJ. Moreover, when power oversupply is expected at the time of executing UC, the PVS output suppression factor was added to the constraint function concerning the supply–demand balance for controlling the scheduled PVS output.…”

“…As a preliminary study on the supply–demand management for the power system with massive PVCs installed, UC‐EDC–based model is used for investigating the effects of PVS output prediction error on the operation schedule for the following day, and so on . It is, however, a challenging task to properly assess the prediction errors of PVS output short‐cycle variation or ramp event with the computation time‐step of 30 min to 1 h of the model to be applied for the above.…”

SUMMARY This paper examines the influence of aggregated power output fluctuation of photovoltaic power generation system (PVS) on the power system frequency focusing on ramp events of aggregated PVS power output. A numerical simulation model of economic load dispatching control (EDC) and load frequency control (LFC) is used together with a PVS power output forecasting model and a unit commitment (UC) scheduling model developed in our preceding study. As a result, in the case of ramp event with long duration and high ramp rate, the frequency violation occurs when the power output of controllable generators with high load‐following capability reaches to upper/lower limit even if the power output of low load‐following capability generators is still available. If the load dispatching scheme is tentatively changed from the conventional EDC using an equal incremental fuel cost rule to, for example, a dispatching policy based on the capacity without the consideration of fuel cost, the aggregated load‐following capability can be kept, avoiding the frequency violation.
