As industries, utilities and regulators take into account the best methods to accommodate our rising want for power generation, price issues weigh closely on their decision-making.
New analysis, nonetheless, reveals that selecting the least costly possibility isn’t all the time the best answer, and even slightly wiggle room on price can present a way more socially, environmentally and politically coherent consequence.
A recently published paper in the journal Joule depends on analysis from Binghamton University Assistant Professor Neha Patankar, who makes use of a way referred to as modeling to generate alternate options (MGA) to systematically map out economically and technically viable planning methods and their trade-offs.
Collaborators on the brand new paper embrace researchers from the Technical University of Delft (the Netherlands), UiT – the Arctic University of Norway, Technical University of Denmark, Princeton University, Technische Universität Berlin and the University of Oslo.
With the rising array of electrical energy generation choices — from fossil fuels and nuclear to photo voltaic, wind and hydropower — figuring out the correct mix of applied sciences is a posh problem that goes effectively past merely choosing the lowest-cost possibility.
“Even a small relaxation of total system cost, as little as 2%, can lead to radically different technology portfolios for meeting growing electricity demand,” stated Patankar, a college member on the Thomas J. Watson College of Engineering and Applied Science’s School of Systems Science and Industrial Engineering. “It highlights how the so-called ‘cost-optimal’ solution is highly sensitive to uncertain assumptions and may provide only a false sense of certainty.”
The strictest price-conscious fashions pushed by synthetic intelligence and machine studying don’t make suggestions primarily based on variables which may be extra essential in the long run, resembling ecological, social, political or environmental results.
“Using MGA to show options that are near-optimal cost can reveal strategies that align with unmodeled objectives such as social viability, resilience to sudden supply disruptions or hedging against policy shifts,” Patankar stated. “Stakeholders can see practically viable consensus solutions hidden by the insistence on cost optimality.”
As local weather change accelerates the shift towards renewable power, researchers like Patankar and her collaborators are working to map out efficient methods for navigating the complicated tradeoffs of the power transition.
“Our main conclusion is that MGA is now accessible and versatile enough to become a standard in improving the reliability and usefulness of the analyses shaping urgent energy transition decisions globally,” stated Francesco Lombardi, an assistant professor at TU Delft and the lead writer of the brand new paper.
“The many organizations that directly use energy planning models for their strategy can immediately pick up our recommendations to enhance the quality of their analyses and ensure that they deliver reliable, practically viable advice.”
