Solar photovoltaic systems continue to expand across the United States due to cost competitiveness, Federal and state incentives, and Renewable Portfolio Standards (RPSs). Transmission Planners and Operators must ensure high levels of grid reliability as increasing penetration levels further affect system variability and generation intermittency. A Time Step Simulation (TSS) is developed to study...
This paper investigates various forms of industrial time synchronization and applies these methods to programmable automation controllers (PACs) for power system applications. PACs have been used in the industry for many control applications, and advancements in synchronization technology have allowed PACs to be used in high-speed control and data acquisition systems. This paper looks at using the...
BPA and WECC utilities are investing resources in phasor measurement technologies and advanced applications utilizing synchronized data. The new production-grade synchrophasor infrastructure opens up opportunities for expanding existing response-based stability controls. A synchrophasor-based RAS scheme is proposed that utilizes both real power and phase angle difference rate-of-change to detect large...

This paper explores utilizing a programmable automation controller (PAC) in a power system relay protection scheme. The adaptive voting scheme (AVS) uses a wide-area measurement system (WAMS) to classify the system operating state, and biases the protection scheme towards security or dependability based on stressed or normal conditions, respectively. The use of an automation controller to integrate...
This paper summarizes implementation of an Adaptive Voting Scheme (AVS), which uses Wide Area Measurements (WAMs) from Phasor Measurement Units (PMUs) to make a classification of the operating state of the power system using decision trees to prevent critical transmission line misoperations. Using commercially available products on the market, this scheme was proved effective and efficient for implementation...
