Документ Energy commitment: a planning of energy carrier based on energy сonsumption(Національний технічний університет "Харківський політехнічний інститут", 2019) Dehghani, M.; Montazeri, Z.; Malik, O. P.Purpose. Energy consumption is one of the criteria for determining the quality of life in a country. Continued supply of energy and the possibility of long-term access to resources require a comprehensive plan. One of the key issues in the field of energy planning is energy carriers. Inthis paper, a new theory is introduced to energy network studies for planning of energy carriers called Energy Commitment. In this theory, an appropriate planning is applied for energy carriers based the final energy consumption. Energy carriers are available either naturally or after the energy conversion process. Energy commitment is modeled on an energy network with the presence of electrical energy, gas energy, transportation section, agriculture section, industrial section, residential section, commercial section, and general section.Документ A new methodology called dice game optimizer for capacitor placement in distribution systems(Национальный технический университет "Харьковский политехнический институт", 2020) Dehghani, M.; Montazeri, Z.; Malik, O. P.; Al-Haddad, Kamal; Guerrero, Josep M.; Dhiman, G.Purpose. Shunt capacitors are installed in power system for compensating reactive power. Therefore, feeder capacity releases, voltage profile improves and power loss reduces. However, determination optimal location and size of capacitors in distributionsystems is a complex optimization problem. In order to determine the optimum size and location of the capacitor, an objective function which is generally defined based on capacitor installation costs and power losses should be minimized According to operational limitations. This paper offers a newly developed metaheuristic technique, named dice game optimizerto determine optimal size and location of capacitors in a distribution network. Dice game optimizer is a game based optimization technique that is based on the rules of the dice game.Документ Planning of energy carriers based on final energy consumption using dynamic programming and particle swarm optimization(НТУ "ХПИ", 2018) Dehghani, M.; Montazeri, Z.; Ehsanifar, A.; Seifi, A. R.; Ebadi, M. J.; Grechko, O. M.In the present article, a new approach of the energy grid studies is introduced to program energy carriers. In this view, a proper plan is designed on the use of energy carriers considering the energy optimum use. Indeed, the proper energy grid is designed by applying Iran energy balance sheet information. It is proper to mention that, the energy grid modelling is done in a matrix form. The electrical energy distribution among power stations is achieved by using the particle swarm optimization algorithm. In the present paper, concerning the dynamic programming method, it is tried to determine a suitable combination of energy carriers.Документ Spring search algorithm for simultaneous placement of distributed generation and capacitors(Національний технічний університет "Харківський політехнічний інститут", 2018) Dehghani, M.; Mardaneh, M.; Montazeri, Z.; Ehsanifar, A.; Ebadi, M. J.; Grechko, O. M.Purpose. In this paper, for simultaneous placement of distributed generation (DG) and capacitors, a new approach based on Spring Search Algorithm (SSA), is presented. This method is contained two stages using two sensitive index Sv and Ss. Sv and Ss are calculated according to nominal voltageand network losses. In the first stage, candidate buses are determined for installation DG and capacitors according to Sv and Ss. Then in the second stage, placement and sizing of distributed generation and capacitors are specified using SSA. The spring search algorithm is among the optimization algorithms developed by the idea of laws of nature and the search factors are a set of objects. The proposed algorithm is tested on 33-bus and 69-bus radial distribution networks. The test results indicate good performance of the proposed method
