Topological Invariants of Principal G-Bundles with Singularities
(Pleiades Publishing, 2018)
principal G-bundle with singularities is a principal bundle π: P¯ → M with structure group G¯ which reduces to a subgroup G ⊂ G¯ on the set M \ Σ, where M is an n-dimensional compact manifold and Σ ⊂ M is a k-dimensional ...
Integration of PV Arrays in DC Power Grids via Unidirectional Boost Converters: A PBC Approach
(Institute of Electrical and Electronics Engineers Inc., 2018)
This paper presents a general control design for photovoltaic systems integrated with Direct-Current power grids by using an unidirectional boost converter. Passivity-based control (PBC) theory is used as a control technique ...
Apparent power control in single-phase grids using SCES devices: An IDA-PBC approach
(Institute of Electrical and Electronics Engineers Inc., 2018)
This paper proposes a passivity-based control (PBC) applied to a supercapacitor energy storage system (SCES) with a single-phase pulse-width-modulated voltage source converter (VSC). The proposed strategy allows to control ...
