EMTP simulation of a STATCOM-Shunts-OLTC coordination for local voltage control

This paper proposes coordinative control method between STATCOM installed within substation and other reactive power resources including shunt reactors and shunt capacitors and OLTC. Voltage/reactive power control has various difficult aspects to control because of analysis and system dynamics error. This coordinative control method suggests practical algorithm regarding system voltage and reactive power status which is easy to implement in substation basis. In normal status, STATCOM-Shunts-OLTC are in operation. The proposed algorithm is tested and verified in EMTP/RV. And this is expected to be applied to control multiple reactive power devices combined with SCADA/EMS system.
