Preparation-dependent oxygen release and apparent carbon deposition of Cu–Fe/ZrO2 oxygen carriers during wheat straw chemical looping conversion

Cu–Fe/ZrO 2 composite oxygen carriers with identical nominal compositions were prepared by mechanical mixing (MM), impregnation (IM), and sol–gel synthesis (SG) to investigate how preparation route affects oxygen release, cyclic stability, gas-product distribution, and apparent c...

Optimal synthesis of wideband shaped-beam array antenna through convex optimization

A linear-programming (LP) framework is introduced for the synthesis of wideband shaped-beam patterns produced by uniform linear arrays (ULAs). The single-frequency feasibility-based LP formulation is extended to a multi-frequency power mask by sampling the normalized spatial freq...

Hierarchical graph reinforcement learning for coordinated dispatch and reconfiguration of active distribution networks

Traditional studies on active distribution networks often optimize operational dispatch and network topology reconfiguration in a decoupled manner, although the two decisions are strongly coupled through power-flow redistribution, controllable-device outputs, and network constrai...

Coordinated Optimization Strategy for Load Aggregator in Distribution Network Considering Demand Response and Peak Regulation Incentive

With the increasing proportion of flexible resources such as distributed generation, energy storage and demand response in new power systems, load aggregators, as an important subject connecting users and the market, face the challenges of complex load types, large differences in...
