Challenge in utility resources management

  • Demand Side Management Programs (DSMs) aim to reduce overall energy consumption as well as the resources used to meet the demand of consumers.
  • The adoption of DSM initiatives is being established by the electric providers to diminish power demand during the critical periods of the power grid.
  • These initiatives mainly depend on implementation costs and convenience for both the utility provider and consumers.
  • Estimating the energy needed to heat a residential building is crucial for thermal performance evaluation.
  • Current DSM programs and DSM systems are based on predicting aggregated utility consumption (i.e. day-ahead or hours-ahead), scheduled utility network control, and utility consumption reduction incentives require communication between the utility provider and utility consumers.
  • Such DSM programs and systems rely on utility network control signals exchanged between the utility grid and the consumers. To provide these exchanges, additional implementation costs are necessary.
  • Such DSM programs may affect the comfort level of the electric utility consumer, adding some resistance to adopt such programs.
  • There is therefore a need for a method and system for managing utility resources, which is more easily deployable and scalable, while proving interesting for both the utility provider and consumers.

Smart energy management system

  • The present technology relates to a method for detecting, in real-time, power grid electric transients, analyzing these transients and providing a performance index from local measurements at the consumer side.
  • The performance index represents the state of power consumption seen by the power network and can be used for load management purposes at the consumer side.
  • The estimation of the power consumption is achieved through real-time signal processing method.
  • This method comprises a measurement unit and analog-to-digital conversion phase, a digital filtering process, an elementary statistical analysis and finally an estimation phase.
  • Technology developed by Prof. Kodjo Agbossou and his team at Université du Québec à Trois-Rivières.

Competitive advantages 

  • Permit a quickly deployable solution for load management responding in real-time and an adaptive manner.
  • Overcome the communications required between the electric provider managing the power grid and the local controller at the consumer side.
  • Permit to implement DSM and grid friendly Home Energy Management System programs at the consuming facility side, based on local measurements and transient analysis.
  • Reduce costs and complexity for a massive deployment.
