This work proposes an analytical method for calculating sensitivity index. The proposed method is based on one-at-a-time measurements and calculates the difference between output values and the base solution to define the impact caused by each parameter in the system. The results indicated that the analytical method provides adequate values for the sensitivity index even when the parameters have minor...
This work proposes different methods to calculate the sensitivity of system parameters based on graphic analysis. From percentages variations in base values of the parameters, one-at-a-time measures are taken to the construction of a graph that expresses the impact on the output caused by variations in the inputs. Two case studies are proposed, with simulated and experimental data, in which the proposed...
Simulation, by resorting to suitable models, is often used by electric utilities in studies related with load forecasting, system reliability, power flow and demand-side management activities, among others. Nowadays, in restructured electricity market scenarios, activities involving buying and selling energy can also be studied through simulation. Different goals for those studies require different...
