The poultry farming is the raising of domesticated birds such as chickens and ducks for the purpose of farming meat or eggs for food. To ensure that the poultries remain productive, the poultry farms in Singapore are required to be maintained at a comfortable temperature. Cooling fans, with power ratings of tens of kilowatts, are usually installed to regulate the temperature in the farms .Besides cooling the farms, the wind energy produced by the cooling fans can be harnessed using wind turbines(WTs) to reduce the farms demand on the grid. The major difference between the situation in poultry farms and common wind farms is in the wind speed variability. In recent years, the research attention on dc grids has been resurging due to technological advancements in power electronics and energy storage devices ,and increase in the variety of dc loads and the penetration of dc distributed energy resources(DERs) such as solar photovoltaic and fuel cells. Many research works on dc micro grids have been conducted to facilitate the integration of various DERs and energy storage systems. In a dc micro grid based wind farm architecture in which each wind energy conversion unit consisting of a matrix converter, a high frequency transformer and a single-phase ac/dc converter are proposed. However, the proposed architecture increases the system complexity as three stages of conversion are required. In this project as an alternative solution we are proposing a dc grid based distribution network. Where the ac output of the wind generators (WGs) in a poultry form are rectified to a common voltage at the dc grid. Most significant advantage of the proposed system is that only the voltage at the dc grid has to be controlled for parallel operation of several WGs without the need to synchronize the voltage, frequency and phase thus allowing the WGs to be turned ON (or) OFF any time without causing disruptions.
