Impacts of 1 MW Solar Power Plants Connected to the Medium Voltage Distribution Network of Ayrancı, Karaman

Abstract

Turkey Solar Energy Potential Map shows that in the southern side of Turkey within a few years, different size of solar power plants
may be integrated to distribution network; but distributed generation and its requirements is not a literally well-known issue in Turkey.
National legislation standards were published by the authorities and as a result of arising applications, distribution companies have started to
integrate renewable power plants in their network as a micro-model (wind, solar, biogas, etc.) of the traditional power plants. Generation
type, line size, state of the load and the distance are very important for voltage profile. This paper presents an overview of the 8 MW solar
plant integrations and analyzes the impacts of them to Ayrancı network using load flow and short circuit analysis methods with Sincal
software and geographical coordinates. Through these analyses, the overloading of the bar, the line and the transformer can be observed
when there is a variable load status in the plant connected to system, and also the strength of the distribution element boundaries can be
observed. After all commissioning, the solar plants can undertake the supply of local energy and it is possible to reduce investment needs for
distribution companies.
