Use of Smart Meters for Energy Savings 節(jié)能智能測量儀的使用

1、use of smart meters for energy savings 節(jié)節(jié)能智能能智能測測量量儀儀的使用的使用 henrik madsen professor 教授教授 green it visit in china contents 內(nèi)容 smart meters and energy savings 智能測量儀和節(jié)能 problem setting 問題設(shè)定 simple tool 簡單工具 advanced tool 先進工具 large scale integration of renewable energy in denmark 丹 麥可再生能源大規(guī)模一體化 green i

2、t visit in china possibilities using smart meters 使用智能測量儀的可能性 estimation of ua and ga values ua和ga值的估算 estimation of energy signature/labelling 能量標簽的估算 estimation of dynamic energy signature 動態(tài)能量標簽的估算 estimation of time constants 時間恒定的估算 full dynamic model of the building 建筑的全動態(tài)模型 green it visit in

3、china energy labelling of buildings 建筑的能源標簽 today building experts make judgements of the energy performance of buildings based on drawings and prior knowledge. 今天，建筑專家根據(jù)圖和先進知識來判斷建筑能源的表現(xiàn) this leads to energy labelling of the building 這導致了建筑能源的標簽 however, it is noticed that two independent experts ca

4、n predict very different consumptions for the same house. 然而，值得關(guān)注的是兩個獨立的專家對相同房屋做出不同的消耗估 計 green it visit in china simple estimation of ua-values ua值的簡單估計 consider the following model (t=day no.) estimated by kernel-smoothing: 考慮以下模型（t=天） the estimated ua-value is: 估計的ua值是： green it visit in china es

5、timated ua-values 估計的ua值 green it visit in china model for the energy dynamics of buildings 建筑能源動態(tài)模型 physical model measurements: 測量測量 (indoor air temperature) 室內(nèi)氣溫室內(nèi)氣溫 heat supply 熱量供應熱量供應 ambient air temperature 周圍氣溫周圍氣溫 solar radiation 太陽輻射太陽輻射 green it visit in china green it visit in china data

6、 數(shù)據(jù) green it visit in china model a 模型a a first proposal for a model (aw=window area) 模型的第一個假設(shè)（aw=窗戶區(qū)域） green it visit in china model validation (model a) 模型確認（模型a） green it visit in china the final model 最后一個模型 the model found by statistical modelling of the building: 本模型是由建筑的統(tǒng)計模型產(chǎn)生 green it visit

7、in china model validation (final model) 模型確認（最后的模型） green it visit in china conclusions smart meters 總結(jié)智能測量儀 reliable energy signature. 可靠的能源標簽 proposals for energy saving: 節(jié)能的提議 replace the windows? 重置窗戶 put more insulation on the roof? 加大屋頂隔熱材料的使用 is the house too untight? . will be implemented in

8、 my house將被 作為“我的家”的補充 optimized control最適當?shù)目刂?optimized use of solar and wind power.最適當?shù)奶柲芎惋L能的使用 green it visit in china green it visit in china integration of renewable energy 可再生能源一體化 in denmark wind power counts for about 22 pct of the total power. 在丹麥，風能占了所有能量的 22% we have tools for: 我們的工具 win

9、d power forecasting 風能預報 solar power forecasting 太陽能預報 optimal planing 最佳規(guī)劃 first 8 weeks of 2007 2007年的最初8個星期 total power and wind power: 總能量和風能 green it visit in china wind power prediction tool 風能預報工具 green it visit in china conclusions 總結(jié) smart meters can provide 智能測量儀能提供 energy signatures / labels of buildings 建筑的能源標簽 time constants for optimal control 時間恒定的最佳控制 advanced knowledge about potentials for energy savings 潛在節(jié)能的先進知識 denmark has a leading position in integr
