Contingency analysis is a key function in the Energy Management System (EMS) to assess the impact of various combinations of power system component failures based on state estimation. Contingency analysis is also extensively used in power market operation for feasibility test of market solutions. High performance computing holds the promise of faster analysis of more contingency cases for the purpose...
The “Smart Grid” refers to various efforts to modernize the power grid through the application of intelligent devices. This paper describes current thinking by members of the Distribution System Analysis Subcommittee (DSA SC) on how distribution system analysis might evolve to support the Smart Grid. Various issues related to Smart Grid and distribution system analysis are identified. The essential...
This paper describes a design process of advanced grid equipment including both dynamic simulations and power-hardware- in-the-loop. A case study concerning the insertion of an energy storage system in a large isolated grid is used as an illustrative example. First, the methodology developed to achieve a real-time simulation of the studied grid from its original dynamic model is presented. The real-time...
The present paper introduces some simulation methods for flicker propagation assessment. The first method is based on current injection into the system matrix of the studied grid. Only one computation is enough to get all nodal voltages of the grid. We can thus deduce flicker propagation coefficient between any two nodes by the ratio of the relative nodal voltages. The second method requires two load-flow...
This panel presentation gives an overview of the DOE/NSF/DHS TCIP Center which is addressing the challenge of how to design, build, and validate a cyber infrastructure for the next generation power grid that can survive malicious cyber attacks while providing continuous power delivery. TCIP's research plan is focused on securing the low-level devices, communications, and data systems that make up...
