optimal conection of wind type distributed generation to typical distribution network considering voltage profile and network harmonic regulation

The scattering distribution generator of the machines work as a power generator exploiting which is possible when connected to power network. The outcome capacity of this unit should not surpass 25 Megawatt in a power network. A combination of these generators which follow the settled capacity condition and link in the same point to the power network will create scattering distributing generator. As the power systems enter a competitive market, it is anticipated that such generators will play a very important role in power industry. These generators are power sources which produce distributed power within the network connected required by consumers' demands. In order to utilize these generators safely and most appropriately in a power network all the standards and principles regarding generators' utilization should be taken into account. Concerning allowed power capacity in connecting generating sources is one of the fundamental issues that should be followed based on settled standards. One of the most important parameters is the existence of hindering harmonics which is caused by power distributing sources and their influences on different bases in terms of size and location of the power generators. In this current project a network with determined base and load is subjected. Harmonic models of transformers, loads, distributing lines, and generating sources are introduced in a harmonic state. Optimization of wind power plant connection to standardized distributing network is done considering the limitation of voltage profile and harmonic state.
