Stability considerations of connecting a large-scale photovoltaic plant to the public grid

In recent years, due to global warming, energy security and environmental problems, interest in renewable energy sources, which are environmentally friendly energy production, has increased worldwide. Accordingly, it attracts great interest in modern energy systems in the installation of large-scale photovoltaic power plants (LSPVPP) connected to transmission lines. In addition to the rising trend, the control and operation problems encountered during the integration of large-scale photovoltaic energy systems into the grid are increasing. A detailed analysis and regulations with limitations are needed to deal with these problems. In this article, a detailed examination of the problems encountered during the connection of LSPVPP to the network will be made. Network regulations created by the countries will be examined. The restrictions to be examined in these regulations will be observed limitations of the grid code used in Turkey. Regarding the problems encountered during the connection of these facilities to the transmission lines; fault ride through requirement (FRT), voltage and frequency, active power and frequency control, voltage control and reactive power limitations specified in Turkey in the first network with the correct design and simulations including regulation will be observed. The evaluations to be made; Suggestions will be made for the establishment of stable facilities with correct design and design and meeting the requirements of the grid regulation. Matlab / Simulink will be used to validate the assessments to be made.
