A v Alue- Tracing Approach to Smart Grid Demonstration Proj Ect Assessment

Non-commonality of the assessment method due to the diversity of member types and characteristics seriously causes deviation in overall and accurate diagnosis of smart grid demonstration project. Taken multilateral participant into consideration, the proposed method models the cost and benefit, according to the direct and indirect value flow, which is based upon the relationship between devices, service and added value. The application of value-tracing in a practical case shows that, compared with conventional power grid benefit calculation methods, value flow analysis makes smart grid assessment more precise and more actual because it calculates indirect value of multiple subjects and members.
