Efforts to significantly boost the usage of renewable power are burdening power grids, leading to increased financial and ecological issues. An effort has created systems and methods to realise low-energy districts. Renewable energy supply fluctuates, and matching its demand and supply is becoming all the more challenging. Smart energy management systems and energy storage space systems are required to accommodate a big share of renewable energy in current energy infrastructure. A project set off to increase the use of on-site renewable power at region level by matching its power need and supply. Undertaking partners began by categorising different district kinds and analysing their different load profiles. They then mapped the gear that can be utilized in a district and examined their overall performance. Thermal storage space and smart control are key components of concept. Thermal storage enables a control system to match the supply and need of heat. Thermal storage technologies had been designed following research on novel storage methods. Team members developed a smart power management system to match supply and demand of electrical energy and temperature at the same time. A full-scale demonstration was successfully carried out by setting up the system in 106 dwellings and 9 commercial spaces in an innercity region under development. A simulation tool to evaluate new types of energy systems for existing and new areas was also created and implemented. To make the developed system appealing to end users and meet their increasing energy demands, the group developed a set of novel business models. They are all based on the freedom of the energy consumed or created within the district, and are incorporated into the system. The project envisioned a sustainable community that strives for financial, environmental and social stability. With fossil fuels expected to run out and the need for energy to boost, current energy supply systems are undergoing radical modifications. It helped enhance a number of types of thermal storage technologies to handle the variability of renewable power. In doing therefore, it demonstrated just how to fully exploit the potential of renewable energy.
