Optimal Siting and Sizing of Hybrid Energy Systems (PV-WTCHP) and Electric Vehicle Charging Stations simultaneously based on Game Theory Approach

This paper proposes a methodogy for practical siting and sizing of hybrid energy system HESs consist of: wind turbine WT photovltatic PV and combined distribution system is considered. Electric Vehicle are seen to have some negative impacts on electric distribution system performance, suchasincreasing power losses, voltage variations and even cutomer energy prices. An important issue is that high penetration penetration of electric vehicle EVs brings heavy electricity demand to the power grid. One effective way to alleviate the impact is to integrate local power generation such as Hybrid Energy Systems (HESs) into charging infrastructure. In this paper at the first stage, candidate buses forinstallation of Hybrid Energy Systems (PV-WT-CHP) and EV charging station. Then, the heat selling possibility of thebuses is determined through the Bus Heating Factor (BHF) using a fuzzy method. Utilizing this factor and the electricalpower to heat ratio of the units, the HESs placement proposal is suggested at the second stage. Moreover, the financialbenefit of investors obtained from heat selling of the CHP units (in Hybrid Energy System) is determined through aneconomic analysis (EA) at this stage. Studying the interaction between EVs and HESs in the distribution system and thefrequency regulation process of candidate buses at the third stage, the financial benefit of the distribution companyobtained from loss reduction and the voltage profile improvement is evaluated through a technical analysis (TA).Finally considering the distribution company and investors as players, the best location and capacity of HESs and EVcharging station will be achieved for installing in the distribution buses using a nash equilibrium point in game theory(GT) approach. The applicability of the proposed method is examined on a sample distribution feeder in the city ofHamadan.Keywords: Hybrid (PV-WT-CHP) Energy Systems (HESs), allocation, electric vehicle charging station, Nodalpricing method, Bus heating factor, Game theory.Submission date: 11 , 11 , 2016Acceptance date: 08 , 11 , 2017Corresponding author: Shahram JavadiCorresponding author’s address: Research Center for Intelligent Power System & Automation, Central TehranBranch, Islamic Azad University, Tehran, Iran.
