Application of Heuristic Algorithms for Rating Optimization of DVRs in an Interline DVR (IDVR) Considering Load Variations in Feeders
Abstract:
In this paper, a heuristic algorithm is proposed to calculate the optimum rating of dynamic voltage restorer (DVR) in an interline DVR (IDVR) considering load variations in feeders. Due to the limitation of active power exchange between DVRs in an IDVR, selection of the appropriate voltage for each DVR in an IDVR should be such that, first, voltage sags in each of the feeders are compensated, and second, IDVR rated kVA and total cost are reduced. For this purpose, an optimization problem in previous studies was proposed to select the rated voltage of DVRs in an IDVR. In that problem, feeder load is assumed to be constant and equal to the rated values, while load variations in feeders affect active power exchange between the DVRs and their injected voltages. Therefore, load variations in feeders in the optimum design of IDVR must be considered. This is the main contribution of current research. Given that in practice the number of time intervals in load curve is high, the solution space of optimization problem will be very large and search the entire solution space is not possible. Thus, in this paper by proposing a convenient strategy based on PSO and GA methods sum of rated kVAs of DVRs is minimized. Furthermore, to demonstrate the capability of proposed method, a comparison with the results of the search of the entire solution space is done.
