Abstract :
The market-oriented risks to the investments of the smart grid is exsited, due to the large investment, long operating cycle and a wide range of management of the smart grid and the uncertainty factors, such as the behaviors of members and volatility of price. And reasonable investment-benefit analysis of the investments will be an important way to prevent risks. The impact of the investment of smart grid on the grid companies is analysised on the operating performance, such as the costs of investment and operation and maintenance and equipment lifetime, and power demand.And the cost-effectiveness model of investments of smart grid is builded, containing an average annual intelligence estimate of investment costs and intelligent benefits. Take smart grid investments in one province as an example, and the results verify the efficiency and rationality of the model.
