METHOD AND APPARATUS FOR EXTRACTING CURVE POINTS FOR CONTROLLING GRID-CONNECTED INVERTERS

Provided is a curve point extraction method including receiving a power control requirement specification for controlling a grid-connected inverter from a server, determining whether a required function included in the power control requirement specification is included in a preset function, determining whether a number of candidate points included in the power control requirement specification satisfies a minimum number corresponding to the required function, determining whether a range of the candidate points satisfies an allowable range of curve points corresponding to the required function, and sorting the candidate points and extracting the curve points based on a curve point extraction algorithm corresponding to the required function.
