    Sensitivity analysis result

    Composed of a list of sensitivity values in pre-contingency and post-contingency states.

    Sensitivity analysis is used to assess the impact of a small modification of a network variables on the value of network functions. A combination of a variable and a function is called a sensitivity factor. It returns the sensitivity values for each factor, and the reference values for each function. The sensitivity analysis API offers the possibility to calculate the sensitivities on a set of contingencies besides the pre-contingency state. The full set of results consists of: - the list of factors - the list of contingencies and their associated computation status - the list of sensitivity values in pre-contingency and post-contingency states - the list of function reference values in pre-contingency and post-contingency states. A sensitivity analysis result offers a set of methods to retrieve sensitivity values or function reference values. For example, you can retrieve a sensitivity value as a double given the ID of a contingency, the ID of a variable and the ID of a function.
