A Transmission Plan Considering Uncertainties Under a Deregulated Market

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. This paper will propose a model for transmission expansion to meet the requirement of the deregulated power market. 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 optimum transmission expansion plan.
