Interruptible load analysis using sequential Monte Carlo simulation

Electric utilities are increasingly examining cost-effective opportunities to utilise demand-side management initiatives, such as interruptible contracts to reduce the need for additional capacity. Techniques are presented for conducting interruptible load analysis using sequential Monte Carlo simulation. A bisection search approach was developed to effectively determine the interruptible load carrying capability. An index, designated the avoidable additional generating capacity, is proposed and a procedure to calculate it is presented. Numerical studies were performed to indicate the possible applications of the proposed techniques.
