Analysis of worst case Power system contingencies using vulnerability frontier
Dawar, Vikas (2010-05-15)One of the most important aspect in a power system network is to make a network secure against unanticipated events. In general, a power system network is always made N-1 secure: any single outage will not lead to ... -
Cascaded Stalling of Induction Motors in Fault-Induced Delayed Voltage Recovery (FIDVR)
Chen, Heng (2011-05-15)In recent years, the phenomenon of Fault-Induced Delayed Voltage Recovery (FIDVR) has increasingly been observed. Air conditioner (A/C) motor stalling is considered as one of the main reasons for the occurrence of delayed ... -
CONSTANT GRID CURRENT CONTROL OF
Kumar, Kanishka (2012-08-26)Variable frequency drives running loads at constant power increase the current drawn from the grid when the voltage sags. This undesirable increase in current stresses the grid. Linear control theory is applied to a model ... -
Load Dynamic Performance Sensitivity Analysis with respect to End-Use Motor Characteristics and Distribution Feeder Networks
Srinivasan, Rahul (2010-05-15)Motor dynamics sensitivity analysis with respect to end-use motor characteristics (inertia, load torque profile, electrical parameters) is presented in this thesis. Mechanical data of motors play a very important role ... -
Optimal Proxy-Limited Lines for Representing Voltage Constraints in a DC Optimal Powerflow
Schlindwein, Michael (2009-12-15)With the recent restructuring of the electric industry away from the vertically integrated monopolies, electricity markets have emerged in various parts of the country. Independent System Operators (ISOs) and Regional ... -
POWER SYSTEM MODELS FORMULATED AS EIGENVALUE PROBLEMS AND PROPERTIES OF THEIR SOLUTIONS
Molzahn, Daniel (2010-12-15)Eigenvalue problems incorporate multiplicative nonlinearities in otherwise linear equations. Two power systems models with multiplicative nonlinearities are reformulated as eigenvalue problems. Reformulation allows for ... -
Safe Control of Thermostatically Controlled Loads with Installed Timers for Demand Side Management
Mehta, Nishant Nikhil (2013-08-25)Motivated in part by the expanded use of renewable power generation, which are often non-dispatchable and intermittent, we examine the role of electric loads in providing ancillary services for demand side management. A ... -
Sensitivity Calculation of Different Parameters for Power Plant Collaboration
Yang, Ziqi (2014-05-18)This paper introduces a dynamic simulation method to simulate a WECC 4 bus power plant model and discusses various optimization approaches to better simulate the model by varying some parameter values. -
A Tool for the Analysis of Market Power Potential in Electric Energy Markets
Borden, Alex (2010-05-15)Market power is the ability of a market participant to alter the market price of a good or service without losing customers to competition. The participant's price is profitably maintained above a competitive level for a ...
