Optimal Operation for Transmission Systems with Uncertainty of Demand Forecasting and Voltage Stability

In recent years, most of the electric utilities have been introduced renewable energy that will increase the power system uncertainty. Thus, the demand curve is hard to predict since the renewable energies fluctuate irregularly. Moreover, it is expected that it will increase the likelihood of voltage instability. In this paper, we suggest the optimal operation method for transmission systems with the uncertainty of demand prediction and voltage stability. The optimal operation that corresponds to the uncertainty of load demand and the operational maintaining the voltage stability can be achieved by the proposed method in this paper.
