President Obama called for doubling the share of renewable energy in the nation's supply in three years. California has a renewable energy target of 33% percent by 2030. These bold commitments need transformational strategies to achieve them. Government policies to achieve the ultimate goal of carbon reduction in electric energy systems are to (i) increase renewable penetration, and to (ii) introduce...
The application of phasor technology is one of the most important next steps in the enhancement of power systems for smart grid technology. Phasor Measurement Unit (PMU) data is here and firmly established as vital to forensic studies. The electric utility industry is now moving at an accelerated pace with new initiatives to bring PMU data into the real-time fold. This panel paper highlights six areas...
While one of the strongest points in a power system is the substation, it still contains what can be described as weak points or points of failure that could lead to major outages. Present paper examines the impact of Superconducting Fault Current Limiter (SFCL) on the transmission substation reliability. To this end, potential application of a SFCL in a practical 138 kV transmission grid is studied...
State and potential federal policies are expected to increase renewable generation in North America in the immediate future. Much of this growth will be from variable resources such as wind generation and solar photovoltaic (PV). As the amount of variable generation increases, the reliability of the bulk power system can be negatively impacted if provisions are not made to accommodate the additional...
Smart Grid initiatives proposed by governments and industry organizations have the potential to support carbon mandates/targets. While the options and scope of the changes that might be deployed within the transmission and distribution system to respond to climate change initiatives, is not yet defined they options could include bi-directional power flow, the increased use of distributed variable...
Recently, there has been great interest in the integration of Distributed Energy Resources (DER) at the distribution level. DERs are potentially valuable providers of ancillary services such as load following and contingency reserve in distribution systems. This will require new control strategies for coordinating their system performance. One issue that has not been addressed sufficiently is the...
The electric power grid is a highly complex system with unique challenges for ensuring safety and reliability of operations. The high degree of interconnectivity and dynamics of loads, sources, and lines has introduced vulnerability. These challenges include such factors as - aging infrastructure, transmission expansion to meet growing demands, distributed resources, congestion management, reliability...
