Integration problems of photovoltaic systems-wind power, solutions and effects on power quality

Abstract

Renewable Energy Sources (RES) are growing steadily in power systems, which is expected to meet most of the electricity demand in the future. Today, solar and wind energy sources are spreading at a great speed, which creates difficulties in handling the discrete nature of solar energy. In this study, the effects of grid integration problem and wind energy (WP) applications of photovoltaic (PV) systems were investigated. The best design of sizing and positioning planning in RES based distributed systems are also examined. In addition, it has been determined that the integration of renewable energybased distributed production into power systems is very difficult and critical. Providing a sustainable energy source in power systems is just one of these challenges. Accordingly, the integration of WP and PV based production into the grid in proportion to the energy source may negatively affect the power system by reducing its reliability. It also sets some rules for connecting generators to the grid to ensure that the system continues to operate well and safely in terms of resource security, reliability and power quality (PQ). Thus, these rules, called network codes, regulate the conditions for transmission and distribution system users. This fundamental issues related article also PQ, the basic rules are desirable for wind turbines in different countries of the grid codes, compliance with the rules of the wind turbines and rules to be complied with wind power plants in Turkey were examined..
