Abstract
Partial shutdown of distribution networks of the Republic of Iraq due to the military conflict and annual growth of demand for electric power has caused a noticeable power shortage. Overload in the networks of the Republic of Iraq has caused an increase in voltage and power losses in the elements of distribution network, which significantly affects the main parameters of the network and indicators of power quality. Calculation of the mode in the software package RasterWin2 confirmed the voltage reduction in the nodes above the permissible values and the increase of active power losses in the elements of the distribution network. One of possible variants of the solution of the problem of reduction of voltage and power losses in the distribution network, at necessary quality of electric power, is the use of photo diesel power plants (PDPP). Additional factors determining the possibility of using the distributed generation in the form of PDPP are climatic features and presence of local hydrocarbons. For the purpose of selection of PDPP connection nodes in the distribution network of the Republic of Iraq, the task of optimization of active power losses was solved on 11 kV buses of 33/11 kV substation, and a certain combination between photovoltaic panels (PVP) and diesel power plants (DPP) was proposed. For criterion of optimality the minimum of active power losses in networks with voltage of 33 kV is chosen, which are compensated by installations of PDPP. On the basis of the optimization task solution it is proposed to install PDPP in three most typical units (10, 15, 23) with total capacity of 2000, 1500 and 1000 kW. The evaluation of the efficiency of the distribution networks of the Republic of Iraq, taking into account the use of PDPP, has confirmed the significant increase of the voltage level in the c
