Flexible Coordinated Planning of Electricity-gas Integrated Distribution System Considering Demand Side Management

With the rapid development of natural-gas fired units and power-to-gas technology, the interdependency of electricity and natural gas distribution network is deepening day by day. It is of great significance to carry out research on the joint planning of them. On the other hand, demand side management has received more and more attention for realizing the target of peak load shifting and improving the security and economy of the system. Given this background, this paper proposed a coordinated planning method for electricity-gas integrated distribution system considering demand side management. Flexible coefficients are introduced to get a balance between economy and security of the system. Incremental piecewise linearization method and auxiliary variable method are put forward to solve the problem simply and quickly. Case study on an electricity-gas integrated system verified the effectiveness of the proposed planning method.
