Direct power control of electrical energy storage systems: A passivity-based PI approach
(Elsevier Ltd, 2019)
This paper proposes a direct power control for electrical energy storage systems (EESS) in ac microgrids. This strategy allows managing instantaneous active and reactive power without using a conventional inner-loop current ...
Current PI Control for PV Systems in DC Microgrids: A PBC Design
(Institute of Electrical and Electronics Engineers Inc., 2019)
This paper proposes a passive PI control for applications of photovoltaic (PV) systems integrated with boost DC-DC converters. The proposed controller guarantees asymptotically stability in closed-loop for the boost DC-DC ...
Group-Theory for the Analysis of Heuristic Algorithms in Power Distribution Systems
(Institute of Electrical and Electronics Engineers Inc., 2018)
This paper applies group theory to four classic problems in power distribution systems, namely: phase balancing, primary feeder reconfiguration, optimal tap setting of voltage regulator transformers and optimal placement ...
Controller design for VSCs in distributed generation applications: An IDA-PBC approach
(Institute of Electrical and Electronics Engineers Inc., 2019)
This paper presents an asymptotically stable global controller design for distributed energy integration in electrical distribution networks using a three-phase voltage source converter (VSC). An invariant Park's transformation ...
Power Flow Analysis in DC Grids: Two Alternative Numerical Methods
(Institute of Electrical and Electronics Engineers Inc., 2019)
This express brief proposes two new iterative approaches for solving the power flow problem in direct current networks as efficient alternatives to the classical Gauss-Seidel and Newton-Raphson methods. The first approach ...
Hand anthropometric study in northern Colombia
(Taylor and Francis Ltd., 2017)
The main purpose of this study is to gather information about the dimensions of the northern Colombian (Caribbean region) population, focusing on the dimensions of the hand and comparing them with measurements from other ...
