Publication number: 20220250500Abstract: An electric vehicle (EV) charging method which considers the EVs heterogeneity, taking into account the absence of any information about future arrivals and departures, and of the amount of time any charging will take. The method further considers both switch on and off possibilities and not an arbitrarily small minimum charging power. In order to achieve all these objectives, the invention defines novel metrics and uses them to construct a dedicated optimization problem. As the charging power is discontinuous, the minimum charging power not being arbitrarily small, the optimization problem is mixed integer by nature. Further, because the mixed-integer optimization is difficult to perform in real-time, the invention proposes a heuristic for reducing the number of integer variables, thus reducing the complexity of the problem.Type: ApplicationFiled: June 13, 2019Publication date: August 11, 2022Inventors: Jagdish Prasad Achara, Cong Wang, Mario Paolone, Roman Rudnik, Jean-Yves Le Boudec, Lorenzo Enrique Reyes Chamorro

Patent number: 11346868Abstract: The method for determining mutual voltage sensitivity coefficients between a plurality of measuring nodes of an electric power network does not rely on knowledge of the network parameters (for example: series conductance and susceptance of the branches, shunt conductance and susceptance of the nodes, etc.). The method uses a monitoring infrastructure including metering units at each one of the measuring nodes, and includes a step of measuring at the same time, at each one of the measuring nodes, repeatedly over a time window, sets of data including values of the current, the voltage, and the phase difference, a step of computing active power, reactive power and values from each set of measured data, and a step of performing multiple parametric regression analysis of the variations of the voltage at each one of the measuring nodes.Type: GrantFiled: April 12, 2017Date of Patent: May 31, 2022Assignee: DEPSYS SAInventors: Joël Jaton, Guillaume Besson, Michael De Vivo, Mauro Carpita, Mario Paolone, Konstantina Christakou, Carl Mugnier, Omid Alizadeh-Mousavi

Patent number: 11204375Abstract: A method for performing synchrophasor estimation of an input signal, whereby the input signal is a sinusoidal power system voltage or current signal, comprising: a. Periodic sampling of a continuous time-domain waveform, consisting of a power system voltage or current signal, to obtain a discrete time-domain function; b. Transforming a discrete time-domain function to a discrete frequency-domain function; c. Estimating from the discrete frequency-domain function the instantaneous parameters of a synchrophasor of the sampled continuous time-domain waveform, the instantaneous parameters comprising a frequency, an amplitude and a phase angle. The method is directed to an improvement of the enhanced IpDFT-based synchrophasor estimation which takes into account interharmonic tones.Type: GrantFiled: June 9, 2017Date of Patent: December 21, 2021Assignee: ECOLE POLYTECHNIQUE FÉDÉRALE DE LAUSANNE (EPFL)Inventors: Asja Derviskadic, Paolo Romano, Mario Paolone

Patent number: 10078318Abstract: A power flow control system for an interconnected power system, the interconnected power system comprising a plurality of electrical subsystems; an abstract framework configured to work as a utility maximizer under constraints (that applies to the electrical subsystems by specifying their capabilities, expected behavior and a simplified view of their internal state); and a plurality of agents. Each agent is responsible of one or a plurality of the electrical subsystems, comprises means configured to express an internal state of the electrical subsystem within a common system of coordinates, and has communication means configured to communicate among agents according to a protocol. The abstract framework means enables a composition of a set of the interconnected electrical subsystems into a further subsystem for which a further internal state is expressed within the same common system of coordinates used before, the further internal state being communicated with other agents according to the protocol.Type: GrantFiled: August 26, 2013Date of Patent: September 18, 2018Assignee: ECOLE POLYTECHNIQUE FEDERALE DE LAUSANNE (EPFL)Inventors: Jean-Yves Le Boudec, Andrey Bernstein, Mario Paolone
