A Transmission Expansion Plan Considering Uncertainties and Risk Assessment Under a Deregulated Market

Conference paper
Part of the Lecture Notes in Electrical Engineering book series (LNEE, volume 293)

Abstract

In a deregulated power market, the transmission is required to supply a nondiscriminatory service. The location of power producers and power purchasers does not matter in terms of participation in national electricity market. Therefore, criteria for transmission planning in a deregulated market are different from those in a monopoly power market. These criteria must be amended to meet the requirement of the deregulated power market. The entrance/closure of the generation units is subject to delay or even cancellation, and it will increase uncertainties for the planning. This paper will propose a transmission expansion plan to meet these requirements. The contingency analysis and nodal price analysis are used to find all the candidate lines to add to the transmission system. Considering the investment cost, operation cost, and risk cost, a method combining the Monte Carlo Simulation and the Greedy Algorithm is proposed to find the optimal transmission expansion plan.
