Simulation of Electricity Production Systems in Autonomous Networks in order to Maximize the Wind Energy Penetration

Wind energy applications are recently characterized as an economic and attractive solution for the urgent electrification problem of most Aegean Sea islands. On the other hand, the fluctuation of daily and seasonal electricity load in almost all island grids, in combination with the stochastic behaviour of the wind, lead to substantial wind energy penetration limits, especially during the low consumption periods of the year. In this context, the present study is devoted to the development and implementation of a mathematical simulation model of the electricity production process in autonomous electrical networks, based on various types of power plants. For this purpose a new reliable and integrated numerical model is developed, using the available information of the corresponding electricity generation system (EGS), in order to calculate the maximum acceptable wind power contribution in the system, under the normal constraints that the system manager imposes.
