  • place attachment and public acceptance of renewable energy a tidal energy case study
    Journal of Environmental Psychology, 2011
    Co-Authors: Patrick Devinewright
    Abstract:

    Abstract Efforts by many governments to mitigate climate change by increasing deployment of renewable energy technologies have raised the importance of issues of public acceptance. The ‘NIMBY’ (Not In My Backyard) concept, although popular, has been critiqued as an appropriate and valid way to explain local opposition. This study applies an alternative approach, empirically investigating the role of place attachment and place-related symbolic meanings in explaining public responses to a tidal energy converter in Northern Ireland, said to be the first grid-Connected Device of its kind in the world. 271 residents in two nearby villages completed questionnaire surveys, three months post-installation, following up preliminary qualitative research using focus groups. Although results indicated predominantly positive and supportive responses to the project, manifest by emotional responses and levels of acceptance, significant differences between residents in each village were also observed. Contrasting patterns of association between place attachment and emotional responses suggest that the project enhanced rather than disrupted place attachments only in one of the two villages. In regression analyses, place attachment emerged as a significant, positive predictor of project acceptance in both places, affirming its value in explaining public response. Place-related symbolic meanings also emerged as significant, with contrasting sets of meanings proving significant in each context. Implications of the findings for research on place attachment and responses to land-use changes, as well as for developers seeking to engage with residents affected by energy projects are discussed.

  • enhancing local distinctiveness fosters public acceptance of tidal energy a uk case study
    Energy Policy, 2011
    Co-Authors: Patrick Devinewright
    Abstract:

    Abstract Tidal energy has the technical potential to form part of a low carbon electricity sector, however, its ‘social potential’ is less clear, as few empirical studies of public beliefs and responses have been conducted to date. This research addressed this gap by investigating a tidal energy convertor in Northern Ireland, said to be the first grid-Connected Device of its kind in the world. Data was collected from 313 residents of two nearby villages using mixed methods, guided by a conceptual framework that avoided ‘NIMBY’ assumptions and instead drew on place theory. Findings indicated strong support for the project, arising from beliefs that the project enhanced local distinctiveness by ‘putting the area on the map worldwide’; appeared visually familiar and helped tackle climate change. These positive beliefs outweighed concerns about outcome and process aspects, which were preponderant in one of the two villages. The project was interpreted to have few positive local economic outcomes, to potentially threaten local livelihoods and local ecology. Moreover, residents expressed cynicism about consultation procedures, and reported low levels of behavioural engagement. Implications of the findings for the literature on public acceptance of renewable energy, and for the emerging marine energy sector specifically, are discussed.

  • cmos current steering logic for low voltage mixed signal integrated circuits
    IEEE Transactions on Very Large Scale Integration Systems, 1997
    Co-Authors: D J Allstot
    Abstract:

    A quiet logic family-complementary metal-oxide-semiconductor (CMOS) current steering logic (CSL)-has been developed for use in low-voltage mixed-signal integrated circuits. Compared to a CMOS static logic gate with its output range of /spl Delta/V/sub logic//spl ap/V/sub dd/, a CSL gate swings only /spl Delta/V/sub logic//spl ap/V/sub T/+0.25 V because the constant current supplied by the PMOS load Device is steered to ground through either an NMOS diode-Connected Device or switching network. Owing to the constant current, digital switching noise is 100/spl times/ smaller than in static logic. Another useful feature which can be used to calibrate CSL speed against process, temperature, and voltage variations is propagation delay that is approximately constant versus supply voltage and linear with bias current. Several CSL circuits have been fabricated using 0.8 and 1.2 /spl mu/m high-V/sub T/ n-well CMOS processes. Two self-loaded 39-stage ring oscillators fabricated using the 1.2 /spl mu/m process (1.2 V power supply) exhibited power-delay products of 12 and 70 fJ with average propagation delays of 0.4 and 0.7 ns, respectively. High-V/sub T/ and low-V/sub T/ CSL ALU's were operational at V/sub dd//spl ap/=0.70 V and V/sub dd//spl ap/0.40 V, respectively.

    Abstract:

    A quiet logic family-complementary metal-oxide-semiconductor (CMOS) current steering logic (CSL)-has been developed for use in low-voltage mixed-signal integrated circuits. Compared to a CMOS static logic gate with its output range of ΔV logic V dd , a CSL gate swings only ΔV logic V T + 0.25 V because the constant current supplied by the PMOS load Device is steered to ground through either an NMOS diode-Connected Device or switching network. Owing to the constant current, digital switching noise is 100x smaller than in static logic. Another useful feature which can be used to calibrate CSL speed against process, temperature, and voltage variations is propagation delay that is approximately constant versus supply voltage and linear with bias current. Several CSL circuits have been fabricated using 0.8 and 1.2 μm high-V T n-well CMOS processes. Two self-loaded 39-stage ring oscillators fabricated using the 1.2 μm process (1.2 V power supply) exhibited power-delay products of 12 and 70 fJ with average propagation delays of 0.4 and 0.7 ns, respectively. High-V T and low-V T CSL ALU's were operational at V dd 0.70 V and V dd 0.40 V, respectively.

  • Active and reactive power management of photovoltaic-based interline dynamic voltage restorer in low voltage distribution networks
    2012 IEEE Energy Conversion Congress and Exposition (ECCE), 2012
    Co-Authors: Ahmed Elserougi, Ayman S. Abdel-khalik, S. Ahmed, A. Massoud
    Abstract:

    A dynamic voltage restorer (DVR) is a series Connected Device that can support the voltage at existing critical loads during voltage sags. Voltage restoration may need active and/or reactive power injection into the distribution feeder. Due to the limitation of the DVR energy storage element, the Interline Dynamic Voltage Restorer (IDVR) can be used to mitigate the voltage sag in distribution systems. In a two-line IDVR system, the active power required for voltage restoration is obtained from the neighboring feeder. The maximum active power that can be injected by the neighboring feeder depends on its load displacement factor. Renewable energy sources and batteries can be Connected across the common DC link to share the required active power in case of insufficient mitigation of the voltage sag by the neighboring feeder or both feeders are experiencing simultaneous voltage sag. This paper focuses on active and reactive power management of a photovoltaic-based (PV-based) IDVR for supporting the system during voltage sags to enhance the system reliability and power quality. A complete strategy with operational constraints for a two-line PV-based IDVR in low voltage distribution networks is proposed in this paper. Simulation and practical results are presented to substantiate the proposed concept.
