BC Hydro's experience on Voltage VAR Optimization in distribution system

A novel Volt-VAR Optimization engine for smart distribution networks utilizing Vehicle to Grid dispatch

“…Generally, most papers have studied CVR (which is a part of VVO) separately. Some papers have focused on voltage and reactive power optimization through improving VVO techniques [7][8][9]12,13,[15][16][17][18]22,29,30]. The predominant feature of these classes of studies is their focus on making the algorithms or implementation techniques more efficient [7][8][9][10][11]16,23].…”

“…IEEE 2030 presents a comprehensive guide for Smart Grid interoperability. Some research papers have tried to address different aspects of Smart Grid and their specifications [11,12,14,18,19,23,24,[26][27][28]37] before IEEE 2030 standard. Most such papers have focused on concepts such as: advantages, challenges and functional requirements of VVO in Smart Grids [1,2,[15][16][17]20,23,39], which have covered the fundamentals of Smart Grid based VVO.…”

“…The literature contains relatively few studies [5,27,37,42] focusing on decentralized-VVO technique which employs local control to optimize the operation of VVO components on a feeder. Moreover, other existing VVO technologies that extend the reach of the VVO from substation to the termination points such as Model-based technology [18,43] and AMI based technology haven't focused on the role of new dispatch-able power sources on VVO.…”

Quasi real-time ZIP load modeling for Conservation Voltage Reduction of smart distribution networks using disaggregated AMI data

“…Several electric power utilities have already defined and implemented CVR projects for the energy conservation and/or peak demand reduction and achieved noteworthy results [10], [16], [33]- [34]. For instance, Canadian electric power utilities such as Hydro-Quebec [16] implemented a voltage regulation and CVR plan in a project called CATVAR using remotely monitored transformers and capacitor banks.…”

“…For instance, Canadian electric power utilities such as Hydro-Quebec [16] implemented a voltage regulation and CVR plan in a project called CATVAR using remotely monitored transformers and capacitor banks. BC Hydro implemented a state-of-the-art DMS to provide a platform to create opportunities to implement leading advanced distribution applications, such as model-based Volt-VAR optimization, and network reconfiguration [10]. Moreover, the target of using dynamic Volt-VAR control in one of Hydro-One projects [33] was to utilize power electronic technologies and devices to keep voltage and reactive power within operational limits [33].…”
