Abstract


Voltage is an important indicator of power quality , power enterprise network loss is an important comprehensive technical and economic indicators . For a long time power system network loss problem is more prominent, without reactive compensation is an effective means of reducing line losses . Improve voltage quality , reduce energy loss is the current focus of the work power supply enterprises . In this thesis, the regional distribution network for a certain amount of reactive power optimization of exploration . On reactive power optimization theory and development are reviewed on the basis , first proposed a simple calculation results are reliable linear programming modeling method, fuzzy constraints and interior point Combination introduced to reactive power optimization control, in order to solve problem solving process is not feasible ; while using an improved branch and bound method for discrete control variables boil . The actual load of the power system is continuously changing , and the load is often difficult to obtain a continuous curve . Common approach is sub-period static . As compensation equipment ( taps and switches ) limits the maximum operating frequency of each control variable has upper bound . Consider the dynamic optimization features can create dynamic optimization model , and through appropriate simplification to reduce the amount of control the number of dimensions and according to some heuristic rules to determine the time of the queue , thus bringing the dynamic optimization into a single static optimization time period . During periods segmentation optimization for some research .
