The challenges of operating, such as voltage control, economic and loss reduction can be reduced by proper utilization of network energy storage. Therefore, there is a great potential for use of energy storage systems from both dimensions of service providers and customers consumption. However, improper use or sitting of energy storages in distribution networks can negatively affect voltage regulation. Distribution networks because of their radial or close to radial structer, and their R/X ratio is high compared to the transmission networks, the loadflows such as Newton-Raphson and … are not suitable for distribution network. Therefore, a forward-backward sweep method is employed with the management of the DG. The genetic algorithm and developed the impedance matrix, have been used to optimizing, because of its accuracy and efficiency. To simulation of allocation and sizing algorithm of energy storage with different scenarios including voltage control in allowable range, considering the effect of increasing PV penetration on the network, carbon dioxide emissions, and economic aspect, are investigated on the 33 and 45 buses network. In order to realistic modelling, the production rate of solar cells is modeled with uncertainty of model. The total network load is also variable every hour. With the battery and PV installation in different busses, the optimal location and size of battery is calculated. The scenarios involved include the analysis of the network behavior in the presence of only a battery, only PV and the simultaneous presence of both, with the distribution of PV power at critical nodes and also by adding the constraints of environmental emission, economic issues and losses to the objective function. The results of investigating the battery placement and sizing in 33 and 45 busses radial distribution networks have shown that the grid voltage in the presence of battery is controlled in allowable range and the system is experiencing fewer fatalities and environmental propagation.
