Stochastic contingency assessment applied to Demand Management Contracts

Electric systems require the necessity of new methods and techniques to assess the security in operation and planning. These techniques must be capable to add the oil variation prices, demand growing and reliability assessment. The consideration of all these variables convert the problem in a large numbers of elements to be evaluated in the operation problem. As a result, this arrogates great times wasted on unnecessary simulation time. Mainly from the point of view of contingency assessment. This paper presents an alternative method for the contingencies assessment considering stochastic contingency selection. Applied in the operation of power system considering the minimum load reduction. This allow offer programs utilizing structured incentive payments to encourage customer enrollment and energy conservation.
