AI‐enabled bumpless transfer control strategy for legged robot with hybrid energy storage system

CAAI Transactions on Intelligence Technology, EarlyView.
Abstract Designing Hybrid energy storage system (HESS) for a legged robot is significant to improve the motion performance and energy efficiency of the robot. However, switching between the driving mode and regenerative braking mode in the HESS may generate a torque bump, which has brought significant challenges to the stability of the robot locomotion.

Salt Cavern Hydrogen Storage for Renewable‐Dominated Smart Energy Systems

IET Smart Energy Systems, EarlyView.
Salt cavern hydrogen storage enables large‐scale, long‐duration energy storage by integrating renewable electricity, electrolysis and hydrogen‐to‐power conversion. It provides multi‐timescale flexibility, supports clean firm capacity and enhances resilience in renewable‐dominated power systems.

Electricity Retailer Hedging Using Fungible Financial Renewable Energy Contracts

Australian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT In energy‐only electricity markets, such as the Australian National Electricity Market (NEM), all electricity is bought and sold within the spot market and energy retailers hedge their load using financial contracts. These interrelated markets are key aspects of the NEM design.

Deindustrialization and demographic change: Evidence from big plant closures and downsizing

Canadian Journal of Economics/Revue canadienne d'économique, EarlyView.
Abstract We estimate the causal effect of big manufacturing plant closures and downsizing on the socioeconomic composition of Canadian cities between 2001 and 2021. Our instrumental variables estimates show that big manufacturing plant closures and downsizing—large local labour demand shocks—lead to less population growth and a shift in the demographic

Greenhouse gases resulting from grid‐connected electricity demand

Contemporary Economic Policy, EarlyView.
Abstract Many businesses would like to claim their electricity use results in no greenhouse gases. Because electricity cannot be traced from specific generators to purchasers, regulators and users propose an approximation. Clean electricity use would meet three conditions, or “pillars.” It must be generated (1) nearby, (2) during the same hour, and (3)
