Abstract
The performance of distribution power systems can be improved through the use of automated devices that are controllable by a centralized control system. This thesis focuses on the aspects of controlling energy demand and efficiency using these devices. This process referred to as Integrated Volt Var Compensation (IVVC). IVVC control makes a distribution more flexible by quickly changing switchable devices to respond to changes in the system. Common implementations include loss minimization, efficiency optimization, and energy demand minimization. This paper discusses the motivation for IVVC, the concepts behind its implementation and effectiveness, historical philosophies on distribution feeder operation. Finally, a proposed methodology to maximize energy reduction is presented. This methodology is similar to measurement-based controls, but adds power flow calculations to come up with the optimal solution. An algorithm was developed and tested for balanced distribution systems to demonstrate its effectiveness. Additionally, case studies are conducted on real-world distribution models using industrial grade software. These case studies demonstrate that the proposed methodology results in reducing the peak and long term demand of distribution systems.
