Day-ahead to intraday energy scheduling operation considering extreme events using risk-based approaches

Demand response programs, energy storage systems, electric vehicles, and local electricity markets are appropriate solutions to offset the uncertainty associated with the high penetration of distributed energy resources. It aims to enhance efficiency by adding such technologies to the energy resource management problem while also addressing current concerns using smart grid technologies and optimization method-ologies. This paper presents an efficient intraday energy resource management starting from the day -ahead time horizon, which considers the uncertainty associated with load consumption, renewable gen-eration, electric vehicles, electricity market prices, and the existence of extreme events in a 13-bus dis-tribution network with high integration of renewables and electric vehicles. A risk analysis is implemented through conditional value-at-risk to address these extreme events. In the intraday model, we assume that an extreme event will occur to analyze the outcome of the developed solution. We ana-lyze the solution's impact departing from the day-ahead, considering different risk aversion levels. Multiple metaheuristics optimize the day-ahead problem, and the best-performing algorithm is used for the intraday problem. Results show that HyDE gives the best day-ahead solution compared to the other algorithms, achieving a reduction of around 37% in the cost of the worst scenarios. For the intraday model, considering risk aversion also reduces the impact of the extreme scenarios.(c) 2023 Elsevier B.V. All rights reserved.
