The research of Professor Lestas is associated with the analysis, modeling and control of large scale networks, using advanced methodologies in control theory and optimization, with a focus on the control of power systems and smart grids. Areas of interest include distributed control and optimisation of microgrids, control of converter-based grids, decentralized schemes for frequency and voltage control, control of hybrid AC/DC networks, demand side management, and the development of generalized frameworks through which robust stability guarantees can be provided despite the complexity of these networks.
