Credit‐Driven Adaptive Grouping for Refined Cooperative Multi‐Agent Reinforcement Learning

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Policy heterogeneity is crucial for achieving sophisticated coordination in complex collaborative tasks, which has emerged as one of the key challenges in multi‐agent reinforcement learning (MARL) in recent years. Notably, the grouping paradigm has made remarkable progress in addressing policy heterogeneity.

Zero‐Current Switching Based Model Predictive Control of a Double‐Extended Overlapped Alternate Arm Converter Used in the VSC–HVDC System

High Voltage, EarlyView.
ABSTRACT The alternate arm converter (AAC) is one of the most efficient multilevel topologies based on voltage source converters (VSCs), which has recently gained attention in various applications, particularly in high voltage direct current (HVDC) systems.

Optimization of Wind‐PV Co‐Generation Systems Using Artificial Bee Colony and Back‐to‐Back Voltage Source Converter

IET Smart Energy Systems, EarlyView.
The Graphical Abstract depicts the proposed Artificial Bee Colony algorithm‐based optimal tuning of PI controllers for back‐to‐back Voltage Source Converters in a hybrid wind–PV system. ABSTRACT This paper proposes a hybrid model‐based back‐to‐back voltage‐source converter (B2B‐VSC) system comprising a Photovoltaic (PV) array and a Permanent Magnet ...

Recommendations to Reform the National Electricity Market (NEM)

Australian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT Australia's National Electricity Market (NEM) was established in the late 1990s. The market is an energy only gross pool with zonal (state‐based) pricing. Over the past 15 years, the system has undergone a profound transformation as large coal‐fired power stations have retired and substantial volumes of large‐scale and embedded behind the ...

Managerial Myopia and Corporate Biodiversity Risk: Disclosure, Concern and Risk

British Journal of Management, EarlyView.
Abstract Recent evidence shows that 70% of market participants view biodiversity risk as financially material, yet only 3.8% of firms provide meaningful biodiversity disclosure. We ask why this gap persists and whether managerial short‐termism explains it.
