On the other hand, establishing new facilities outside the city requires an expensive grid extension. In this study, the proposed hybrid power system (HPS) models were analyzed to meet the energy demand of the dispersed industrial facilities out of cities. In addition, sensitivity analyses were made by considering the distance to the national grid (DNG) and the discount rate (DR) changes of the region where industrial facilities will establish. Micropower optimization program HOMER (NREL, US) was used to simulate the system. As a result of the analyzes, it has been determined that on-grid systems are more economical if the distance between the national electricity grid and the energy demand is assumed to be less than 125 km. Furthermore, it has been that the DR change creates a gray region between the break-even points define for on/off-grid systems (125 km= HPS = 175 km). Likewise, it was determined by a sensitivity analysis that grid extension capital cost (GECC) and DR increases reduce the break-even distance (BED) up to 50 km and that off-grid HPSs are more economical after 100 km. According to the results obtained, the study has the quality of guiding the investors about the optimal system set up in the light of technical and economic parameters. © 2021 Chamber of Turkish Electrical Engineers.en10.23919/ELECO54474.2021.9677827info:eu-repo/semantics/closedAccessbreak-even distanceeconomic dispatchenergy storageGrid extensionhybrid power systemrenewable energysensivity analysisEconomic analysisElectric energy storageElectric load dispatchingElectric power system economicsElectric power transmission networksEnergy managementRenewable energy resourcesSensitivity analysisBreak-even distanceDiscount ratesEconomic DispatchGrid extensionHybrid powerHybrid power systemIndustrial facilitiesRenewable energiesSensivitySensivity analyseSchedulingConference Object11172-s2.0-85125235286
