The paper presents aspects related to the connection of renewable sources of energy to the grid and focuses on the Photo Voltaic Power Plant (PVPP). The correlation of this process with Power Quality (PQ) issues and conditions for certification of each plant in accordance with regulations are included in our work as well. Results of measurements of PQ in the Points of Common Coupling (PCC) in the...
The paper presents the impact of connecting Renewable sources to the Smart Grid with regard to improving Power Quality aspects. The impact of integrating renewable sources on Power Quality indices in the grid wes analyzed and the measures for avoiding the negative impact are included in the paper. Challenges coming from the integration of renewables – variability and uncertainty and the correlation...
This paper presents results of power quality monitoring collected from transmission system operator (TSO) and several distribution system operators (DSOs) from Romania. The power quality monitoring system is realized in accordance with actual technologies, economic criteria, performance standards and technical codes issued by the Romanian Energy Regulation Authority (ANRE). The implementation of power...
Two types of Power Quality Monitoring Systems (PQMSs) — one for TSO and other for DSOs, in accordance with Performance standards and Technical Codes of the Romanian Energy Regulation Authority — ANRE were published. The connection to the grid of the renewable sources could determine the increasing of the emissivity of perturbations and the necessity of the propagation study in order to determine the...
World wide the wind power plants are located far away from the existing interconnection substations to the power system. Therefore, compensation methods are considered for the reactance of long distance cable connection. High voltage DC transmission cables for wind power plants interconnection to the grid can also be considered and used. In the present paper, the problems raised by AC cables, from...
The smart grid paradigm for the electric power systems is encompassing an increasingly adoption of distributed generation all over the world. This trend requires the input from flexible alternative current transmission systems (FACTS) devices, which can be used to increase transmission capacity, improving stability and dynamic behavior, and ensure a better quality of energy by controlling several...
The present paper deals with the case study of an existing ac arc furnace facility. A field measuring campaign was carried out for an industrial consumer. One of the many aspects of power quality that can affect electricity users is voltage fluctuation that causes lights to flicker. The main power quality indices regarding flicker levels are reported in the paper with reference to the current standards.
