“…While work in the broader energy decarbonisation field makes use of technological advancements in renewable energy and energy storage [67,68], a step change is required from the energy consumption domain. In this context, the household sector has an increasingly important role to play, not least because of the proliferation of rooftop solar energy [69], smart meters and sensors that all contribute to a paradigm shift from energy consumers to energy prosumers [70,71].Our study focused on the early stage of development (pre-prosumer) of the energy user and specifically on the links between environmental predisposition and behaviour, attitude and habits in energy use. In this context we confirmed the positive relationship between environmental predisposition and activities that aim to reduce energy consumption (such as the replacement of incandescent with low energy lightbulbs).…”

Environmental knowledge, pro-environmental behaviour and energy savings in households: An empirical study

2016

Energy consumption in households comprises over a quarter of total energy use in the UK [1]. Human behaviour is one of the main factors that can influence domestic energy consumption, together with the physical properties of the dwelling, climate, number and demographic profile of occupants, household income, lifestyle, and appliance ownership and use [2][3][4][5]. Indeed, variation in residents' behaviour can cause significant differences in energy consumption between dwellings with otherwise similar characteristics (e.g. household size, income, and building energy performance) [3,6]. It is therefore important to understand influences upon behaviour in households as these in turn have implications for domestic energy use. In this respect, strategies to stimulate pro-environmental behaviour represent one means of modifying behaviour in households in order to promote energy conservation and reduce environmental impact [7].Pro-environmental behaviour is a form of environmental action that 'consciously seeks to minimize the negative impact of one's actions on the natural and built world ' [8, p.240], and 'only refers to those personal actions that are directly related to environmental improvement ' [9, p.325]. Such environmental actions can be performed individually or collectively, and may be direct or indirect in their approach to mitigating harm to, and improving, the environment [9]. Pro-environmental behaviours can also be influenced by internal factors such as environmental awareness, values and attitudes [10] and external factors such as social norms, interaction with other individuals and financial constraints [11,12].In this study we assess how environmental knowledge influences pro-environmental behaviour in households. We establish and confirm links between knowledge about the environment and energy, actions on Environmental knowledge, pro-environmental behaviour and energy savings in households: An empirical study AbstractIn this paper we evaluate the impact of knowledge about environmental and energy issues on potential pro-environmental behaviour in households, specifically relating to behaviours, attitudes and habits towards energy use. Our results are based on an empirical survey and we find significant correlations which indicate that residents with positive environmental values and greater environmental knowledge are more likely to demonstrate energy behaviours, attitudes and habits which lead to energy saving activities in households. This is further supported through a Principal Component Analysis (PCA), which suggests that energy saving behaviour may also vary according to gender and employment status. Conversely, we find only limited evidence of statistical associations between environmental predisposition and knowledge, and ownership and frequency of use of household appliances. We argue that our results contribute to the significant body of literature supporting the role of knowledge in active engagement with energy issues. This study is timely following closely policy developments in activ...

“…Efficiently integrating distributed RE generation systems [3][4][5] is a key research topic because the most used renewable energies-photovoltaic (PV) solar energy [6,7], wind energy [8,9] and marine energy [10]-are intermittent and more difficult to store [11] and integrate without affecting the quality of the electrical network [12] or the electricity prices [13]. The current proliferation of small-scale urban PV in buildings [14] and urban wind generators [15] can help home electricity consumers become also producers ("prosumers") [16] using the smart grid (SG) [17,18] and micro-grids (µ−Gs) [19] concepts.…”

Optimizing the Structure of Distribution Smart Grids with Renewable Generation against Abnormal Conditions: A Complex Networks Approach with Evolutionary Algorithms

et al. 2017

Abstract:In this work, we describe an approach that allows for optimizing the structure of a smart grid (SG) with renewable energy (RE) generation against abnormal conditions (imbalances between generation and consumption, overloads or failures arising from the inherent SG complexity) by combining the complex network (CN) and evolutionary algorithm (EA) concepts. We propose a novel objective function (to be minimized) that combines cost elements, related to the number of electric cables, and several metrics that quantify properties that are beneficial for SGs (energy exchange at the local scale and high robustness and resilience). The optimized SG structure is obtained by applying an EA in which the chromosome that encodes each potential network (or individual) is the upper triangular matrix of its adjacency matrix. This allows for fully tailoring the crossover and mutation operators. We also propose a domain-specific initial population that includes both small-world and random networks, helping the EA converge quickly. The experimental work points out that the proposed method works well and generates the optimum, synthetic, small-world structure that leads to beneficial properties such as improving both the local energy exchange and the robustness. The optimum structure fulfills a balance between moderate cost and robustness against abnormal conditions. Our approach should be considered as an analysis, planning and decision-making tool to gain insight into smart grid structures so that the low level detailed design is carried out by using electrical engineering techniques.

“…From the simulation it appears that the saving in terms of primary energy of cold storage based configuration is generally lower than that of the electric battery based plant storage. In [21] is reported an analysis aiming to increase the value of PV for the prosumers. In this paper different solutions were introduced to increase the flexibility of PV system output to balance energy demand by managing the operation of a GSHP, as well as the use of thermal and electric storages.…”

The paper examines a solar electric driven heat pump serving an office building located in southern Italy. To satisfy space heating and cooling demand a heat pump activated by electric energy available from solar photovoltaic plant equipped with an electric storage is here considered. Dynamic simulations to evaluate the thermo-economic performance of this system, varying photovoltaic peak power (4.5-7.5 kW) and electric battery capacity (3.2-9.6 kWh), are carried out. The proposed system achieves primary energy saving and equivalent dioxide carbon emission reduction up to about 82 % in comparison to the reference conventional system based on a natural gas fired boiler and an electric chiller. The results show that the solar energy system is more competitive when there is no battery storage and government incentives will be provided.
