Publication number: 20220373989Abstract: A method of controlling assets connected to an electricity distribution grid is disclosed. For each of a plurality of assets to be configured, a trained neural network model is provided, which takes an asset configuration as input, the asset configuration specifying a response of the asset to variations in one or more operating conditions detected at the asset, and outputs one or more performance indicators relating to the operation of the asset when operated using the asset configuration. The outputs of the neural network models are provided as inputs to an optimization function. A search process optimizes the optimization function by varying asset configurations for the assets. The final asset configurations are then used to control the assets to provide a coordinated demand response service.Type: ApplicationFiled: October 23, 2020Publication date: November 24, 2022Applicant: Centrica Business Solutions Belgium N.V.Inventors: Brecht DIERCKX, Renaud BRUNELIERE, Stef PEETERS, Filip DELEERSNIJDER, Bert CLAESSENS

Publication number: 20220190599Abstract: A method of controlling assets connected to an electricity distribution grid operating at a predetermined grid frequency is disclosed. The assets comprise assets supplying electrical energy to and/or consuming electrical energy from the grid, with at least some of the assets being configurable to adjust energy flow to or from the grid to counteract grid frequency fluctuations. The method includes configuring an aggregate response by a group of assets to fluctuations in the grid frequency, wherein the aggregate response comprises respective adjustments of energy flow between each of the group of assets and the grid. The adjustments are arranged in combination to counteract a fluctuation in grid frequency. A divergence is detected between a first grid frequency measured in a portion of the grid comprising a first asset of the group of assets and a second grid frequency measured in a portion of the grid comprising a second asset of the group of assets.Type: ApplicationFiled: March 24, 2020Publication date: June 16, 2022Applicant: Centrica Business Solutions Belguim N.V.Inventors: Bert CLAESSENS, Jonas ENGELS

Patent number: 11341396Abstract: A deep approximation neural network architecture which extrapolates data over unseen states for demand response applications in order to control distribution systems like product distribution systems of which energy distribution systems, e.g. heat or electrical power distribution, are one example. The method is a model-free control technique mainly in the form of Reinforcement Learning (RL) where a controller learns from interaction with the system to be controlled to control product distributions of which energy distribution systems, e.g. heat or electrical power distribution, are one example.Type: GrantFiled: December 26, 2016Date of Patent: May 24, 2022Assignee: VITO NVInventors: Bert Claessens, Peter Vrancx

Patent number: 10804702Abstract: Energy loads, sources or batteries exchange mathematical models with each other to form clusters of devices that together provide a service (self-reliance, frequency control, etc.) to a grid operator. Models are exchanged before or after forming clusters; a particular model is used to control its own device and is also used by another load/source to influence its control policy. Heuristics and an optimization technique (using models) are used to form a cluster of devices. Exchanging models obviates the need for a central entity to directly control loads/sources, and the need to exchange real-time data between loads/sources, providing resilience against communication failure. A service manager (demand-response aggregator) sends a service or technical constraints to loads/sources to form clusters on their own. Negotiation between manager and clusters occurs to form consensus on a response.Type: GrantFiled: October 11, 2018Date of Patent: October 13, 2020Assignee: Centrica Business Solutions BelgiumInventors: Bert Claessens, Jonas Engels, Stef Peeters, Jan-Willem Rombouts

Patent number: 10516266Abstract: A method or system for controlling an energy or power supply network having a coordination centre, a plurality of local end-user units and a communications network linking the local units and the coordination centre and a supply network connecting the local units and the coordination centre for energy or power supply. The supply network has constraints that limits power or energy consumption at at least one of the local end-user units. The method or system is adapted so that the coordination centre transmits a control signal indicating a degree of imbalance of the system to the at least one of the local end-user units, and the at least one local end-user unit is adapted to transmit a reaction signal to the coordination centre indicative of a power schedule for the local unit.Type: GrantFiled: May 22, 2014Date of Patent: December 24, 2019Assignee: VITO NVInventors: Fedor De Ridder, Bert Claessens, Sven De Breucker

CLUSTER CONTROL OF HETEROGENEOUS CLUSTERS OF THERMOSTATICALLY CONTROLLED LOADS USING TRACKER DEVICES
Publication number: 20190129368Abstract: Control methods, systems and controllers of devices in an electrical or heat distribution network which devices can be, for example, particularly or mainly thermostatically controlled loads (TCL) such as heat pumps. The methods are based on modeling a network with representative simulated tracer devices. Preferably, only a limited number of simulated tracer devices are used, i.e. limited in number compared to the number of devices in the electrical or heat distribution network. The simulated tracer devices are preferably governed by and have characteristics that are similar to those of actual devices in the electrical or heat distribution network or are representative of a major type of such devices. These simulated tracer devices can be used to represent behavior, for example, of an entire cluster of homogeneous or heterogeneous TCLs.Type: ApplicationFiled: April 29, 2016Publication date: May 2, 2019Applicants: KATHOLIEKE UNIVERSITEIT LEUVEN, VITO NVInventors: Sandro IACOVELLA, Geert DECONINCK, Bert CLAESSENS -
