International Congress on Innovation Regional Economic Development December, 2012 Realize stable supply in the supply chain of distribution using power storage equipment when electricity demand is fluctuant Li Xiaodong School of Management, USTC,Hefei,Anhui and 230026,China Abstract In some areas, personal demand for electricity power is small and rigid, and the load demand at different times is fluctuant. Thus，it is difficult to adjust demand fluctuations through pricing regulation at a local scale. The cost of power production would be significantly reduced if the demand becomes stable. In the view of system engineering, our research intends to make the supply chain for power distribution stable and optimized via using storage equipments in active distribution network. In this paper, we want to find a stable supply power load and appropriate capacity of the equipment. Power storage device serves as a warehouse, and the cost under three cases is discussed. © 20 11 Published by Elsevier Ltd.

Most countries and regions are making their own plans for electricity power development in accordance with the smart grid. China has proposed a three-stage plan to promote the construction of strong and smart grid . The first stage is the pilot phase (2009-2010), which focuses on strong and smart grid” development and planning, the set of technical and management standards, and the development of critical technology and equipment. The second stage is the comprehensive construction phase (2011-2015), which focuses on speeding up the construction of the UHV power gri
