Optimal Simultaneuos Placement of Distributed Generations and Capacitor in Distribution Systems Considering Demand Response

Nowadays the tendecy of using distributed gereration is increasing rapidly by evergrowing of polulation and energy consumption. Determining the optimal sitting and sizing of distributed generation would lead to network technical indexes mprovement such as losses and voltage. Capacitor banks also known as the most common and economical way of reactive power compensation. Also with deregulation of power system, new ways of load and loss reduction must be used inevitably. One such way is applying demand response program on costumers. In this thesis which is a multi-objective optimal placement problem, we have investigated the simultaneous placement of distributed generation and capacitor banks considering demand response program to increase productivity of distribution system. Wind turbines and photovoltaic, and I/C and CAP programs are used as distribution generation and demand response program, respectively. Capacitor banks are supposed to be fixed. Active and reactive loss reduction, voltage index improvement including voltage profile and voltage stability, and distribution company benefit enhancement are the objective considered here. Different senario were provided in order to examine the effect of demand response programs on this problem. To do this optimization, League Championship Algorithm (LCA) was chosen. The proposed method was tested on IEEE 33 and 69 bus standard systems and 135 bus Sarein actual system. Results evaluation had shown the effectiveness of proposed method in network technical indexes improvement considering demand response programs, so distribution system stability and productivity was increased.
