1. Lo, Yuan-Liang. Integrated Volt/Var Controls for Implementing Conservation Voltage Reduction.

Degree: PhD, Electrical Engineering, 2017, NSYSU

Conservation voltage reduction (CVR) study has been conducted for decades and practiced by many utilities, including Taiwan Power Company, to deal with the short term operation problems and conduct energy conservation. To ensure effective distribution feeder level CVR operations, the load behaviors of equipment at the customer side and the distribution transformers under varying voltage situations have to be studied and validated. Due to the advancement of Distribution Automation (DA) system, Supervisory Control and Data Acquisition (SCADA) system and the Advanced Metering Infrastructure (AMI), accurate distribution transformer load and feeder models could be established by exploiting the data available from these system. In this dissertation, real and reactive power data measured at substation, distribution feeders and transformers are used to study the effects of on-load tap changer (OLTC) operations on the distribution transformers loading. A procedure that uses AMI and SCADA data is proposed to validate feeder node loads and detect possible database errors concerning the distribution transformers phase connections. Validated feeder and node load models are then used to perform distribution feeder state estimation to build the on-line feeder operation model. With the close to real-time distribution feeder models, an integrated voltage volt/var control scheme including OLTC, shunt capacitors and feeder tie switches operations, is proposed and demonstrated to achieve multi feeder level CVR operations that could lead to greater energy saving and ensure the voltage quality at each load point.
