Due to the penetration of renewable energy sources increasing in South Korea, problems
related to system reliability have been emerging. Thus, localized control methods have also been
gaining attention as one of the measures. However, due to the AOs (asset owners) lacking management
experience of coordinating resources between the BESS (battery energy storage system)
and the renewable device, there have been multiple issues related to damages caused by fire. Thus,
the governmental reliability committee in South Korea has recently mandated an order adding
reliability constraints to the SoC (state of charge) management and incentives for the AOs to follow
the reliability constraints as specified, despite concerns from the AOs that the order possibly
reduces their revenues. Thus, this study provides a structured analysis, for the first time, on how
the incentive and the reliability constraints influence and interact with each other in coordinated
operating schemes between BESSs and renewables as integrated scheduling systems. In the base
case, the current scheduling method was applied. In case 1, profit maximization was introduced to
confirm the effectiveness of the structured operation. In case 2, a reliability constraint was added,
and a reliability constraint with incentives was added in case 3 to confirm the effects thereafter on the
revenue streams.
