Методика обоснования технических и экономических параметров сетевой ветроэлектрической станции для условий Сирии

Abstract

In this study, a methodology is developed to evaluate the technical and economic parameters of a grid-connected wind power plant in Syria. The methodology was used for designing a grid-connected wind power plant in the area close to the Al-Sukhnah town (in Homs province), which is one of the most promising areas in Syria to build wind farms. Technical assessment of a 12 MW grid-connected wind power plant, which consists of 8 wind turbines with rated power of 1.5MW for each one, is performed using the WindPRO software. The following tasks are carried out in WindPRO: the microscale numerical modeling of the wind flow of the area with consideration the terrain and roughness, determination of wind resources at wind turbine tower height, selection of suitable wind turbine and definition of energy production. The results of the technical assessment show that the wind power density in the power plant site at wind turbine tower height is 333–459 W/m 2 with average annual wind speed of 6.5–7.7 m/s, energy production is 38391.1 MWh/year with consideration the losses, capacity factor is 36.5% with full load hours of 3199 h/year. Economic assessment of the considered power plant is performed in Excel program. The following economic indicators are calculated in Excel: net present value (NPV), discounted payback period (DPP), internal rate of return (IRR), profitability index (PI), the normalized cost of energy (LCOE). The results of calculations show that the proposed grid-connected wind power plant is completely profitable for conditions in Syria.
