Abstract

The demand for electricity is continuously growing due to the development in community's macro-economic parameters; Population and the Gross Domestic Product (GDP). Currently, electricity is mainly generated from conventional sources including fossil fuels (oil, coal, gas, etc.) and nuclear fuel. The increase in demand increases the concerns about depletion of fossil fuels, increasing of carbon dioxide (C02) and other emissions, environmental pollution, and climate changes. Global energy agencies have been urged to look for sustainable and environment friend resources. Renewable energy resources especially wind and solar resources are found ambitious sources that can be developed to share other resources in supplying sustainable environmental friend power due to their economic benefits as compared with other resources and technologies. Energy generated from wind is growing faster than other renewable resources especially at areas with proper wind speed and characteristics capable to generate high power at small land and the possibility to interconnect wind networks with distribution or transmission power networks. Predictability of wind availability and characteristics is limited; therefore, the output of wind turbines cannot be controlled to the same extent as conventional generation technologies. This study involves assessing the impact of interconnecting a 50 MW wind plant at different penetration levels into a 132-kV grid powering a region in the sultanate of Oman isolated (islanded) from the main national grid. The assessment includes mutual impacts on power quality and flow, grid voltage flickering and performance of the network and the farm under steady state and disturbance conditions. The wind plant is constructed from an 18-equal capacity DFIG wind turbines modelled using the simulation from MA TLAB/Simulink available in the college. Parameters of control and operation parameters were developed to fit the wind plant operating conditions. The penetration levels considered in the research include I, 9 & 18 wind turbines in operation respectively which represent 5.5 %, 50 % and 100 % of the maximum farm generation capacity. The research outcomes revealed that penetrating the wind plant at the levels mentioned above provide high accuracy of compliance with the national and international standards and codes and that it shall not conflict the requirements of power quality and security of supply restricted in grid code and regulations. The outcomes obtained also provide high degree of confidence for integrating the wind plant with the existing grid network at the proposed point of common connection (PCC) without any additional extra works required on the existing network rather than those required for adaptation requirements.
