Study on Cross-Area System Operation Utilizing Pumped-Storage Hydro
with Bulk Penetration of PVs

In Japan, PV as renewable energy source (RES) is expanding rapidly. However, if the PV penetration becomes too large, the regulation capability for maintaining the system frequency will be insufficient. Where such a problem arises, cross-area system operation that uses regulation capability of other systems through interconnection lines is being studied. This paper proposes the method of maintaining regulation capability by pumped-storage hydro in other electric power systems through changing the base tie line power flow.
