This paper compares methods for converting system limits into market signals. one classification of methods is according to reliability driven (TLR and similar) versus market driven (LMP and similar) methods. a second classification is according to d

Demand relief from customers can help a utility (or any "load serving entity") solve a variety of problems. There exist all sorts of different demand management programs that utilities use. A critical issue is the incentive paid to the customer to pa

Market equilibrium conditions can be derived from more general dynamic equations describing the marketplace. Dynamic equations provide insights into the behavior and stability of markets which are not available from static models. For example, market

The change in the loading margin to voltage collapse when line outages occur is estimated. First a nose curve is computed by continuation to obtain a nominal loading margin. Then linear and quadratic sensitivities of the loading margin to each contin

This paper discusses the merits of an analytical method for determining the location and amount of series compensation to increase the steady state power transfer capability in the power system based primarily on cascading line overload consideration

This paper studies congestion management based on congestion pricing as may be done by an independent power system operator. Four main concepts are discussed: congestion pricing can lead to the same solution as an optimal power flow; pricing need not

Solution of a set of linear equations Ax=b is a recurrent problem in power system analysis. Because of computational dependencies, direct methods have proven to be of limited value in both parallel and highly vectorized computing environments. The pr

The conjugate gradient method has been suggested as a better alternative to direct methods for the solution of certain large sparse linear systems Ax=b; where A is symmetric and positive definite. Efficiency considerations often require that the conj

Power system loading margin is a fundamental measure of a system's proximity to voltage collapse. Linear and quadratic estimates to the variation of the loading margin with respect to any power system parameter or control are derived. Tests with a 11

This paper presents a way to derive power oscillation damping control strategies for flexible AC transmission system (FACTS) devices, and derives these laws for the four major types of FACTS devices using an energy function (Lyapunov) method. All con
