▼ Residential space and water heating accounts for around 13% of the greenhouse gas emissions of the UK. Reducing this is essential for meeting the national emission reduction target of 80% by 2050 from the 1990 baseline. One of the strategies adopted for achieving this is focused around large scale shift towards electrical heating. This could lead to unsustainable disparity between the daily peak and off-peak electricity loads, large seasonal variation in electricity demands, and challenges of matching the short and long term supply with the demands. These challenges could impact the security and resilience of UK electricity supply, and needs to be addressed. Rechargeable Thermal Energy Storage (TES) in residential buildings can help overcome these challenges by enabling Heat Demand Shifts (HDS) to off-peak times, reducing the magnitude of the peak loads, and the difference between the peak and off-peak loads. To be effective a wide scale uptake of TES would be needed. For this to happen, the benefits and impacts of TES both for the demand side and the supply side have to be explored, which could vary considerably given the diverse physical, thermal, operational and occupancy characteristics of the UK housing stock. A greater understanding of the potential consequence of TES in buildings is necessary. Such knowledge could enable appropriate policy development to help drive the uptake of TES or to encourage development of alternative solutions. Through dynamic building simulation in TRNSYS, this work generated predictions of the space and water heating energy and power demands, and indoor temperature characteristics of the UK housing stock. Twelve building archetypes were created consisting of: Detached, semi-detached, mid-terrace and flat built forms with thermal insulation corresponding to the 1990 building regulation, and occupied floor areas of 70m2, 90m2 and 150m2. Typical occupancy and operational conditions were used to create twelve Base Case scenarios, and simulations performed for 60 winter days from 2nd January. HDS of 2, 3 and 4 hours from the grid peak time of 17:00 were simulated with sensible TES system sizes of 0.25m3, 0.5m3 and 0.75m3, and water storage temperatures of 75°C and 95°C. Parametric analysis were performed to determine the impacts and benefits of: thermal insulation equivalent to 1980, 1990 (Base Case), 2002 and 2010 building regulation; locations of Gatwick (Base Case) and Aberdeen; heating durations of 6, 9 (Base Case), 12 and 16 hours per day; thermostat settings of 19°C, 21°C (Base Case) and 23°C, and number of occupiers of 1 person and 3 persons (Base Case) per household. Good correlation was observed between the simulated results and published heat energy consumption data for buildings with similar thermal, physical, occupancy and operational conditions. The results allowed occupied space temperatures and overall daily and grid peak time energy consumption to be predicted for the range of building archetypes and parameter values considered, and the TES size necessary for a desired HDS…

▼ In the residential sector there is a high energy saving potential, especially regarding
heat demand. A promising energy technology is the
heat pump. It operates at a higher efficiency than conventional heating systems and it eliminates the need for natural gas and as a results less primary energy is consumed and less CO2 is emitted. The most common
heat pump types use electricity. This means that
heat pumps cause an additional load on the electrical grid. This additional load causes
demand peaks that might exceed the current grid capacity. In that case not all
heat demand is satisfied.
In order to satisfy all
heat demand grid capacity exceedance should be prevented. A predictable solution would be to reinforce the grid capacity by replacing transformers and cables, however this is relatively expensive. Therefore other measures are assessed regarding their ability to prevent capacity exceedance and their costs. Besides grid capacity expansion also thermal energy storage,
heat demand reduction, and
heat demand shifting are assessed. Additionally limiting the number of
heat pumps is included.
Grid capacity expansion,
heat demand reduction and thermal energy storage, when implemented individually, can prevent capacity exceedance. Based on their annualized investement costs, capacity expansion and limiting the number of
heat pumps are the least expensive measures at 40 resp. 0 €/household/year.
Heat demand reduction and thermal energy storage and far more expensive at 1,100 resp. 700 €/household/year.
When all the costs are included, which are the annual change in energy costs and the annualized investement cost for the
heat pump and measure, then grid capacity expansion and limiting the number of
heat pumps are the least expensive at 690 resp. 690 €/household/year. The annual costs with
heat demand reduction and TES are 1,090 resp. 1,560 €/household/year.
Primary energy saving and CO2 mitigation is achieved with the implementation of
heat pumps. The lowest specific costs for primary energy saving and emission mitigation costs are found for
heat demand reduction with 120 €/MWhprimary saved and 0.60 €/kg CO2 mitigated.
Under the used base assumptions shiftin to
heat pumps might not be economically viable, if all costs are included and charged to the end-consumer. The viabitily can be improved by lower investment costs, subsidies, larger price difference between electricity and gas and improving of the coefficient of performance. Also investment costs of measures can be reduced by finding combinations of measures and allocating measures to specific households.

▼ Wuxi Sino-Swedish Eco-City, a pilot city region with an area of 2.4 km2, is a demonstration project for innovation in energy technology and integrated smart city solutions in China. After the 1st phase of the project, general outlines of the city’s energy system were drawn and applicable technologies are provided. However, no work has been performed on building electricity load projection and load analysis. This thesis will therefore firstly focus on establishing the building electricity load projection model, using simulation software STELLA. Then the model is scaled up for the whole city region. The simulation results show that there is foreseen to be electricity peak in summer and winter, due to the cooling and heating demand. Based on simulation results, an electricity DSM (demand side management) strategy should be implemented in order to balance the load. Peak load shifting strategy is thus chosen to be investigated. Two technology options (ice-storage system and thermal storage system), which could be implemented to balance the electricity peak, is analyzed by scenarios. Also, commercial feasibility of implementing such technologies is discussed.
