Solving energy ordering problem with multiple supply-demand using Bilevel optimization approach

Abstract

We develop in this paper an energy ordering problem with multiple energy supplying sources and multiple traders trying to satisfy customers’ demands. Such a supply chain network is split of three main layers: the set of energy generation plants (suppliers), a set of traders trying to expect and satisfy customer’s demands dispatched. Following the new investment in renewable energy, customers have the option to choose the nature of its electricity. Customer choice has an impact on the future energy supply chain. For that, we deal with the customer choice in our considered problem. Motivated by this architecture, we propose an evolutionary algorithm-based on bi-level optimization model is developed to handle this problem. The performance of the proposed model is evaluated by numerical experiments based on real-world data.
