Price and procurement optimization in hybrid competitive power supply chain under different bidding strategies
Published on 2026-05-20 by @OXFORD
Abstract: AbstractPower retailers procure electricity from generators and sell it at government-guided prices. Renewable energy electricity and fossil-fueled electricity compete in the market, with the government providing subsidies for renewable energy consumption. The price and procurement optimization of the hybrid competitive power supply chain under different bidding strategies contributes to the sustainable development of the power industry. The main findings of this study show that the total profit[...]
Our summary: This study analyzes price and procurement optimization in a hybrid competitive power supply chain with varying bidding strategies. It finds that simultaneous bidding maximizes retailer profits and aligns closely with centralized supply chain profits. Increased government subsidies for renewable energy lead to lower wholesale prices and altered procurement behaviors among retailers and generators.

Experimental analysis of soil thermal diffusivity for optimizing surface geothermal energy systems in arid environments
Published on 2026-05-12 by @OXFORD
Abstract: AbstractIn this research, the thermal behavior of shallow subsoil in Ghardaïa, Algeria, is experimentally investigated, with a focus on surface geothermal energy systems. From March 2020 to November 2023, air, surface, and subsurface temperatures (0–5 m) and other parameters such as solar radiation, humidity, wind speed, precipitation, and air pressure have been monitored. It was found that soil thermal diffusivity is a decreasing function of depth, with values of 7.31 × 10−7 m2/s and 5.[...]
Our summary: This research investigates soil thermal diffusivity in Ghardaïa, Algeria, focusing on surface geothermal energy systems.
