INTEGRATION PROBLEMS OF PHOTOVOLTAIC SYSTEMS-WIND POWER, SOLUTIONS AND EFFECTS ON POWER QUALITY

Abstract

In power systems, Renewable Energy Sources (RES) are growing steadily, which is expected to meet a large proportion of electricity demand in the future. Nowadays, solar and wind power sources are spread with great speed, which copes with the discrete nature of solar energy, creating difficulties in its use. This study examines the effects of the grid integration problem of photovoltaic (PV) systems and wind energy (WP) applications. The best design of sizing and positioning planning in renewable-based distributed systems is also examined. In addition, it has been determined that the integration of renewable-based distributed production into power systems is quite 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 network in proportion to the energy supply may adversely affect the power system by reducing its reliability. This study sets out some rules for generators to be connected to the grid to ensure that the system continues to operate well and safely in terms of source safety, reliability, and power quality (PQ). Thus, these rules, called the network code, regulate the conditions for the transmission and distribution system users. This paper also fundamental issues related to PQ, the basic rules are prompted for wind turbines in different countries of the network codes, compliance with the rules of the wind turbines and the rules must comply with the wind power plants in Turkey is examined.
