Original abstract
The operational reliability of isolated mini-grids is constrained by voltage instability arising from weak networks, high renewable energy penetration, and evolving rural demand. Demand Response (DR) emerges as a cost-effective and flexible approach to stabilising such systems by reshaping electricity consumption. This study proposes a conceptual Voltage-Centric Demand Response (VCDR) framework, derived from a structured critical review, to examine how demand-side flexibility can contribute to voltage stability in isolated mini-grids. It employs simulation and field studies to evaluate DR control logics, load classes, system structures, and reported performance gains. Although modelling results predominantly support cost savings, reliability improvements, and demand control, a notable gap persists between the theoretical foundations of voltage-centric DR and its practical implementation in mini-grids. Key challenges remain underexplored, including communication architectures, socio-technical constraints, and the co-design of renewable energy systems. Emerging technologies such as artificial intelligence, edge computing, blockchain, and digital twins are identified as potential enablers of scalable and resilient DR systems. Conceptually, the study proposes a hierarchical control framework and an adaptive DR algorithm; however, these lack empirical validation in real-world community settings. While DR has the potential to stabilize voltages in isolated mini-grids, its practical implementation remains fragmented and at an early stage, indicating significant research and deployment gaps.
