© 2015 IEEE.As the electricity market transits into deregulation, customers and generators are given the liberty of deciding on the bid functions they submit and the amount of transmission rights they purchase in the market. These determine the payoffs they achieve from the market. In this paper, we evaluate how generators maximize their payoffs achieved from the market by making strategic decisions about the bid functions they submit and the transmission rights they purchase in the network. Strategical interdependency between decisions for when there are 2 or more generators in the market is also considered and modelled using matrix game. A Nash equilibrium reflecting the strategies the generators should pick is then identified using the max-min theorem. The application of the max-min theorem on the matrix game is modelled as a mixed integer linear programming problem. The proposed matrix game is applied and analyzed on 2 bus and 3 bus systems.

© 2015 IEEE.This paper presents the application of bi-level programming to determine the profit maximization for transmission investor in deregulated power markets. We consider a deregulated market comprising merchant transmission investors responsible for transmission expansion and a central market operator responsible for market clearing. The problem is solved using two levels of optimization: Upper level problem, where the objective of the transmission merchant investor is to maximize profits and a Lower level problem, where the objective of the market operator is to maximize the social welfare of the generators and the customers. Transmission investment decisions made in the upper level adjust the transmission constraints in the lower level. The optimal solutions obtained in the lower level are used by transmission investors to calculate the transmission congestion price and profit. The bi-level model is applied on test systems and the results are consistent with the analytical method available in literature.

© 2016 IEEE.This paper studies the application of an accelerated Benders decomposition algorithm using local branching on a transmission expansion planning (TEP) problem. TEP analyses the trade-off between investment cost of adding network capacity and load curtailment cost of existing network capacity. The problem is formulated as a mixed (0-1) programming problem which is tedious to solve through conventional Benders decomposition. Local branching is used to accelerate this algorithm by dividing the feasible region of the problem into some smaller sub-regions and then using a generic solver to find the best solution in each of these sub-regions. By strengthening lower and upper bounds at earlier stages of the decomposition algorithm, local branching helps reduce number of Benders iterations to solve the TEP problem. The efficacy of this technique is demonstrated by comparing with classical Benders decomposition when applied to a 46-bus power transmission network.
