The development of dynamic energy control mechanisms for food retailing refrigeration systems

国家电网在5%的极窄发电利润率下运行。网络分发基础设施老化，更换成本高昂。电网正受到不断增加的可再生能源发电系统的输入的挑战，这些系统不能提供稳定的负荷。为了稳定电网，现在的战略重点是开发市场，帮助电网控制需求和供应，所谓的需求侧响应（DSR）。然而，需要大规模的示范项目来建立行业对DSR机制的兴趣和信心。在这次演示中，我们将开发和提供能够使食品零售制冷系统与DSR关税挂钩的系统。这是一个具有挑战性的项目，因为食品零售商通常经营分布在英国各地的大型机器网络。对冰箱操作性能的任何改变也必须在不侵犯或危害食品安全的情况下进行。然而，安全交付DSR食品制冷系统可能会产生重大影响。英国的冷链目前被认为消耗了14%的电力。

The National Grid is operating under a very narrow generating margin of 5%. Network distributioninfrastructure is aging and expensive to replace. The Grid is being challenged by an ever increasing input ofrenewable generation systems which do not provide a consistent load. To stablise the Grid it is now a strategicpriority to develop markets which help the Grid control demand as well as supply, so called demand sideresponses (DSR). However, large scale demonstration projects are required to establish industry interest andconfidence in DSR mechanisms. In this demonstration we will develop and deliver systems which can enablefood retailing refrigeration systems to be linked to DSR tariffs. This is a challenging project as food retailers aretypically operating massive networks of machines distributed throuhgout the UK. Any changes to refrigeratoroperational perfromance must also be conducted without infringing or jeopardising food safety. However, safedelivery of DSR to food refrigeration systems could have significant impact. The cold chain in the UK is currentlythought to consume 14% of all electricity generated.
