Community-scale Energy Demand Reduction in India (CEDRI)

CEDRI是一个由赫里奥特-瓦特大学、印度理工学院(IIT)德里、印度理工学院孟买和Tiruchirappalli国家理工学院在可持续建筑、电力电子、需求建模和能源行为方面的专业知识组成的联合体。该项目将通过将需求综合模型应用于印度案例研究，为家庭减少/管理需求提出明确的指导，以确保向印度社区提供未来有弹性的电力供应。该项目认为忽视供应限制是一个关键风险，可能会阻碍未来的需求减少战略。虽然许多国家在家庭能源使用和通过当地能源网络提供能源方面都发生了重大变化，但印度的变化速度尤其显著。住房存量的“更新率”很高(新建住房占住房存量的比例比许多发达国家高得多)，同时，向这些家庭供电的方法正在发生变化(例如，太阳能光伏等分布式可再生发电的增长)。如果要在这种已经不确定的情况下计划进一步的改变，采取全社会范围的减少能源需求战略的形式，那么必须了解这些措施的全面影响。将冷却需求降至最低、控制/管理电器负荷和鼓励分布式发电都应在以下方面得到推广：i)与正常运行的本地电力网络保持一致和相辅相成；ii)涉及可能被社区接受的措施，而不是仅仅具有利基吸引力。CEDRI项目将允许通过应用的聚合算法对社区电力需求进行建模，将个别建筑需求概况的小样本转换为社区级别的概况。在与住户开展调查和讲习班后，该项目将确定在这些地区可能取得成功的减少需求的措施(由真实的案例研究社区和经验数据提供信息)，并将这些措施应用于社区需求模型，以量化潜在的影响。将充分调查这些变化改善当地能源网络的能力，以便能够以改善该网络的关键特性(如频率、电压和峰值需求)的方式来管理被认为能成功降低总能源需求的措施。因此，该项目将提供指导，确保减少需求的方法与用于向居民社区供电的方法在未来的时间尺度上“共同演变”，这些时间尺度已经存在相当大的不确定性。

CEDRI is a consortium of expertise in sustainable buildings, power electronics, demand modelling and energy behaviours across Heriot-Watt University, Indian Institute of Technology (IIT) Delhi, IIT Bombay and the Tiruchirappalli National Institute of Technology. The project will, through the application of demand synthesis models to Indian case-studies, propose clear guidance for demand reduction/management in households to ensure future-resilient provision of electricity to Indian communities. The project sees a neglect of supply limitations as being a key risk that might hamper future demand reduction strategies. Whilst many countries are seeing significant change in the use of energy in homes and the provision of that energy through local energy networks, the pace of change recorded in India is particularly notable. The "refresh" rate of the housing stock is high (with new build constituting a much higher percentage of the housing stock than many developed countries) and, simultaneously, the approach to delivering electricity to those homes is changing (e.g. the growth in distributed renewable generation, such as solar photovoltaics). If further change is to be planned amongst this already uncertain landscape, in the form of community-wide energy demand reduction strategies, then a full impact of such measures must be understood. Minimising cooling requirements, controlling/managing appliance loads and encouraging distributed generation should all be promoted in a way that i) is consistent and complementary to a functioning local electricity network and ii) relate to measures that are likely to be accepted across communities, rather than having only niche appeal.The CEDRI project will allow for community electricity demand modelling through applied aggregation algorithms, converting small samples of individual building demand profiles into community-level profiles. After carrying out surveys and workshops with householders, the project will identify the demand-reducing measures likely to succeed in such regions (informed by real case-study communities and empirical data) and apply these to the community demand models to quantify potential impact. The ability of such changes to improve the local energy network will be fully investigated, such that measures deemed to successfully reduce total energy demand can be managed in a way that improves key characteristics of that network (such as frequency, voltage and peak demand). The project will therefore provide guidance that will ensure that approaches to demand reduction "co-evolve" with the methods used to supply electricity to residential communities, over future timescales that already have considerable levels of uncertainty.
