Multi-elements and multi-dimensions risk evaluation of smart grid

In the development course of smart grid, risk evaluation can be applied for smart grid to lead the decision maker to achieve scientific plan, so that blind investment and significant risk loss may be avoided. Aiming at the reasons and benefits of risk management for smart grid in this paper, firstly, different risk of smart grid can be identified from five aspects, including financial risk, security risk, technical risk, management risk and policy risk. These basic risk factors almost can cover any fields of smart grid. Secondly, based on risk elements identified, multi-dimensions risk assessment matrix method is developed to evaluate the risk of smart grid considering the time and the regional development nature of local smart grid. Finally through the analysis of relevant cases, some change regularity of risk can be obtained due to the property of time and regional development diversity of smart grid.
