Energy Efficiency Engineering
Description
Renewable energy sources play an important role in supplying consumers with clean energy, one of these sources that are included in energy diversity is also wind turbines and solar panels. However, their integration is a multidimensional challenge, considering their fluctuations in production that depend on climatic conditions, as well as the situations created in different work regimes. One of the conditions for their reliable operation remains stability and safety during operation. One of the factors for the stability and continuous and safer operation of wind turbines remains the coordination and selectivity of the action of the relay protections, through which, during different regimes and events, the continuity of their operation is preserved.The paper takes into consideration the analysis of some fault cases and the action and the role of the selectivity of the protections in maintaining the electrical parameters and their operating range in the electrical system, especially in the power balance. The paper relies on the methodology of building models and simulations of different cases, the impact of selectivity on the work of wind turbines and solar panels. The cases of design and selectivity of protections during short circuits, outages, or other occurrences of various elements such as; lines, transformers and busbars in the respective substations. The study has been elaborated in substations of the power system of Kosovo, where through comparisons and simulation models it has been achieved in finding comparative results with an impact on the safety of the operation of wind turbines in the substations of the power system. The paper provides an overview of the results that show the challenges of integrating renewable resources into the power system.
