Optimization-based time-and-level-of-use price setting for an energy retailer
In our framework a retailer wants to determine the optimal Time-and-Level-of-Use tariffs (TLOU) to sell energy to a population of smart homes. TLOU is an energy price structure where the prices vary depending on the time and the level of consumption. This problem is formulated as a bilevel optimization problem.

Strategic bidding for demand response aggregators: An inverse optimization approach
This paper presents optimal pricing design for Demand response in electricity market. The problem is formulated as a linear inverse optimization by an aggregator. Demand flexibility has been quantified and presumed to be the solution for the forward problem. The goal is to find the inversely optimal price signals to maximize the aggregator’s profit.

The Canadian contribution to limiting global warming below 2 degrees: Insights from NATEM
This presentation identifies different decarbonization pathways that would allow Canada to participate in a global mitigation effort to prevent climate changes. We analyse four GHG mitigation scenarios with increasing levels of mitigation efforts for 2050 using the NATEM regional optimization model. The main transformations in the energy system include significant energy conservation and efficiency improvements, greater penetration of electricity in all end-use sectors (up to 64% of total consumption in 2050), as well as an important increased use of bioenergy in 2050. On the supply side, this translates into a rapid decarbonization of electricity production and a shift away from fossil fuel production and imports.

Challenges in energy policies for the economic integration of prosumers in electric energy systems
The accessibility and reducing cost of distributed renewable energy sources are stimulating the emergence of small-scale residential prosumers who can produce and consume electricity. Such prosumers may increase the uncertainty of consumption behavior, reduce consumption from the grid, and eventually disconnect from the grid. However, they may remain connected, and their energy potential can provide flexibility for the overall system. We present an analysis of energy policies promoting disconnection and propose a reconsideration of current schemes for the economic integration of prosumers in the energy system.
