Introduction
Funded by Horizon 2020, REACT will demonstrate the potential of the large-scale deployment of renewable energy systems (RES) and storage assets on geographical islands to bring economic benefits, contribute to the decarbonisation of local energy systems, reduce greenhouse gas emissions (GHG) and improve air quality.

This paper presents a decentralized informatics, optimization, and control framework to enable demand response (DR) in small or rural decentralized community power systems, including geographical islands. The framework consists of a simplified lumped model for electrical demand forecasting, a scheduling subsystem that optimizes the utility of energ...
The world is experiencing a fourth industrial revolution. Rapid development of technologies is advancing smart infrastructure opportunities. Experts observe decarbonisation, digitalisation and decentralisation as the main drivers for change. In electrical power systems a downturn of centralised conventional fossil fuel fired power plants and increa...
A downturn of centralised conventional fossil fuel fired power plants and increased proportion of distributed power generation adds to the already troublesome outlook for operators of low-inertia energy systems. The role of an emerging decentralised energy sector allows separation of local energy needs from major power networks. However, the divers...
Policy and new technologies are transforming the energy landscape in the UK. Centralised control of electrical generation and unidirectional distribution have a finite part in a sustainable energy system. Subsidies have encouraged an increase in distributed resources. At the same time closure of larger fossil-fuelled power plants is reducing system...
This paper presents the development of a digital Proportional Integral Derivative (PID)-like adaptive controller and its application on Heating, Ventilating and Air Conditioning (HVAC) systems. The HVAC process model is often approximately described as a first-order-plus-deadtime (FOPDT) model, with process parameters which can vary with time due t...
Most governments are applying financial instruments and other polices to encourage distributed renewable electricity generation (DREG). DREG is less predictable and more volatile than traditional forms of energy generation. Closure of larger fossil-fuelled power plants and rising share of DREG is reducing system inertia on energy networks such that...
Decentralised Frequency Control
In this paper, a prototype proactive decentralised demand-side electrical frequency regulation tool is proposed and evaluated. Most governments aim to meet ambitious CO2 reduction targets by applying financial instruments and other polices to encourage Distributed Renewable Energy Generation (DREG). Increasing energy demand, combined with the varia...
