This paper describes a design process of advanced grid equipment including both dynamic simulations and power-hardware- in-the-loop. A case study concerning the insertion of an energy storage system in a large isolated grid is used as an illustrative example. First, the methodology developed to achieve a real-time simulation of the studied grid from its original dynamic model is presented. The real-time...
By taking into account the fluctuations of renewable energy based power production (photovoltaic panels) and the ancillary services supply to a microgrid (improvement of the availability and capacity of the power from Renewable Energy Source, uninterruptible supply of critical loads, micro grid power quality improvement, peak shaving, load shifting, reactive power supply/compensation etc.), this paper...
In this paper a graphical modelling tool is proposed to develop a fuzzy logic based supervisor. This tool facilitates the analysis and the determination of fuzzy control algorithms adapted to complex hybrid systems. To explain this methodology, the association of wind generators, dispersed generator and storage systems are considered. The performance of this supervisor is shown with the help of simulations...
The goal of this work is to develop a supervision strategy for hybrid generation systems. This strategy must allow to improve the grid insertion of wind turbine generators (WTG) by associating them some storage systems and foreseeable decentralized generator (FDG). To maintain a reference power and to contribute to the primary frequency control with a hybrid generator based on variable speed WTG,...
To maintain a power reserve to contribute to the primary frequency control with a variable speed wind generator, a fuzzy logic based multivariable control strategy is proposed in this paper. The main result of this paper is to shown that it is possible to create a regular reserve whatever the wind speed without any wind speed measurement. The performance of the proposed primary frequency control strategies...
