Description
Summary:•To consider the uncertainty of load, the range of load has been taken for the load flow solution.•The deviation of the load from its base value can be taken different for different bus.•In the results, lower and upper limit of the total system cost are given. The paper reports on the solution of the capacitor placement problem in distribution system considering uncertainty in the variation of loads. Solution techniques available in the literature generally consider load variation as deterministic. In the present paper uncertainty in load variation is considered using fuzzy interval arithmetic technique. Load variations are represented as lower and upper bounds around base levels. Both fixed and switchable capacitors have been considered and results for standard test systems are presented.
