This paper describes a methodology for transmission expansion planning (TEP) within a deregulated electricity market. Two objective functions including investment cost (IC) and congestion cost (CC) are considered. The proposed model forms a bi-level optimization problem in which upper level problem represents an independent system operator (ISO) making its decisions on investment while in the l...

Load information plays an important role in deregulated electricity markets, since it is the primary factor to make critical decisions on production planning, day-to-day operations, unit commitment and economic dispatch. Being able to predict the load for a short term, which covers one hour to a few days, equips power generation facilities and traders with an advantage. With the deregulation of...

It is well documented in the literature that inadequacy of the analytical models has been a primary reason for the low economic stability of deregulated power industry. Some of the modeling inadequacies can be attributed to the difficulties of analyzing nonzero sum multiplayer stochastic games that are inherent in deregulated power market operations. This paper presents a two-tier game theoreti...

Market power assessment is a prime concern when designing a deregulated electricity market. In this paper, we propose a new functional market power measure, termed transmission constrained network flow TCNF , that takes into account an AC model of the network. The measure unifies three large classes of long-term transmission constrained market power indices in the literature: residual supply ba...

In recent decades, the traditional monopolistic energy exchange market has been replaced by deregulated, competitive marketplaces in which electricity may be purchased and sold at prices like any other commodity. As a result, deregulation of industry produced demand for wholesale organized marketplaces. Price predictions, are primarily meant to establish clearing price, have become significant ...

E®ective competition in wholesale electricity markets is a necessary feature of a successful electricity supply industry restructuring. We examine the degree of competition in the California wholesale electricity market during the period June 1998 to September 1999 by comparing the market prices with estimates of the prices that would have resulted if owners of instate fossil fuel generating fa...

This paper presents a stochastic equilibrium model for deregulated natural gas markets. Each market participant (pipeline operators, producers, etc.) solves a stochastic optimization problem whose optimality conditions, when combined with market-clearing conditions give rise to a certain mixed complementarity problem (MiCP). The stochastic aspects are depicted by a recourse problem for each pla...

In this paper, Generalized Predictive Control (GPC) algorithm is applied to design automatic generation control (AGC) systems in deregulated and networked environment. The proposed AGC approach can be used to deal with the effects caused by power market and communication networks. Finally, the developed scheme is implemented in a two-area AGC system, and the simulation results show the effectiv...

Bidding competition is one of the main transaction approaches in a deregulated electricity market. Locational marginal prices (LMPs) resulting from bidding competition and system operation conditions indicate electricity values at a node or in an area. The LMP reveals important information for market participants in developing their bidding strategies. Moreover, LMP is also a vital indicator fo...
