| dc.description.abstract | Although most distribution systems have benefited from state-of-the-art microprocessor-based devices and modern communication technologies, their design, operation, and control principles have remained unchanged for decades. However, with the deregulation of energy markets and the world being pushed towards the sustainable use of resources and renewable energies, an ever-increasing number of small-scale generation projects are being developed and incorporated into the distribution level, bringing with them a great deal of technical challenges, and defying the traditional operation of the distribution system. In this research work, a protection and control strategy based on the microgrid concept is proposed for a MV feeder containing distributed generation with the aim of attaining a superior integration with the grid when compared to traditional radial distribution systems. To accomplish this, the functional requirements, and the architecture for a microgrid control system are defined based on IEEE Std. 2030.7. Then, the performance of the distributed generation during steady-state and the transition between microgrid operation modes is assessed under the IEEE Std. 1547 requirements. Subsequently, the impact of the proposed microgrid islanding strategy on service restoration and interruption costs is evaluated for the severe cold load pickup (CLPU) conditions that may ensue during restoration following extended outages. This analysis is carried out for typical weather conditions in the winter season in Canada when the penetration of heating load is higher than other seasons. In this context, a detailed overview of the CLPU phenomenon is presented beforehand, including a recompilation of several models intended for power system planning and operation purposes, giving particular attention to the physical modelling of thermal loads. | |
