Conservation of Voltage Reduction (CVR) technology is getting fame globally to achieve the reduction in peak load demand and energy consumption in the distribution network. In this paper, a smart grid enabled CVR scheme for Volt-Var control (VVC) operation has been proposed. The proposed scheme operates with the help of Volt-Var control & optimization (VVC&O) functions of the advance distribution...
Smart grid technologies are expected to increase system efficiency and reliability using advancement in automation, communication, computation, and optimization. Several control algorithms have been developed or enhanced for operation and control of smart distribution grid. In recent years, volt/var control (VVC) algorithms have been proposed for energy saving in distribution systems due to advancement...
Steady state voltage rise problem resulting from the integration of DGs at lower voltage levels can be a major impediment to the growth of distributed generation capacity. With the steady implementation of the smart grid technologies throughout the existing distribution networks, the online voltage control can be achieved. The voltage profile has to be estimated first along the distribution networks...
For conventional radial distribution network, the voltage profile of each feeder can be controlled within the reasonable level by adjusting the OLTC transformer terminal voltage and local shunt capacitors. But for active distribution grid, this traditional voltage regulation scheme may fail. Therefore, a novel coordinated voltage control strategy is proposed to regulate voltage of distribution network...
Smart grid technologies are expected to increase system efficiency and reliability using advancement in automation, communication, computation and optimization. Several control algorithms have been developed or enhanced for operation and control of smart distribution grid including Fault Detection, Isolation and service Restoration (FDIR), Optimal Feeder Reconfiguration (OFR), and Volt/Var Control...
Intermittency of variable renewable generation (VRG) requires time sequence analysis, over a defined interval, to adequately capture VRG characteristics. As the penetration level rises, connected VRGs inject as much energy as the existing resource permits. It is therefore, essential to develop a technique that maintains system voltage profile, and facilitates the smoother integration of VRGs into...
Dominion Virginia Power's Conservation Voltage Reduction program has demonstrated energy savings of up to 4% by optimizing off-peak voltage. The key innovation is incorporating end-of-line voltage data from every customer meter, which eliminates the need to maintain an electrical model of the feeder. CVR is accomplished via DMS control of the load tap changer based on voltage feedback from AMI meter...
In this paper the smart grid features of Demand Response (DR) and Volt/Var Control (VVC) are integrated in a distribution system. A coordination scheme for DR and VVC is developed and simulated on American Electric Power's 12.47 KV distribution feeders. Multi Agent System (MAS) is used to establish the coordination scheme by the exchange of distribution network model in real time. Varying levels of...
This paper summarizes the history of volt/VAR control at Progress Energy Carolinas (PES) for the transmission to distribution and distribution systems. PEC has transitioned from a volt/VAR control system that incorporated local control of capacitors and regulators to an automated system that provides remote control of feeder capacitor banks. Currently PEC is implementing a Distribution System Demand...
