  7. Abstract:
  8. Nowadays, with the development of the generation and storage technologies of electrical energy, increasing attention to environmental issues, and interest in improving the reliability of electrical energy distribution networks, the motivation to develop the distribution networks from pssive to active mode. Although, the utilizing of electrical energy storage systems (EESs) made technical and economic analysis of power system more complicated, but some of these challenges have faciliated by microgrids. Indeed, microgrids, as low voltage and medium voltage networks, can provide a set of significant benefits at the level of distribution networks by improving energy efficiency, power quality, and increasing reliability for consumers. The Energy storage systems can mitigate peak load with storing energy during low load and selling them when electricity price is high. in addition to preventing the cost of the high cost of electricity at peak times, also helps to reduce the maximum load. they So far, the majority of studies on the use of storage devices at the distribution level have covered most of the technical dimensions of this issue and discussed the economic aspects of the theorem. In this regard, this research tries to design a suitable framework for determining the location, capacity and number of optimum energy storage batteries in a sample grid, and the economics of investing in batteries with various manufacturing technologies. Compare the reliability costs with the planning horizon. Therefore, in this thesis, we aim to determine the location, the number of required modules and the optimum capacity for energy storage batteries dispersed in a grid with two operating modes connected to the network and the island according to demands, constraints And our main criteria are in every case. For this purpose, we used the 33-base IEEE distribution network as a sample grid, and in each case, we compared the simulation results
