考虑多微网接入的气电-交通耦合系统分布式规划方法OA北大核心CSTPCD

The surge of electric vehicles(EVs)intensifies the deep coupling between transportation network and gas-electricity distribution network,and the widespread penetration of microgrids aggregates geographically adjacent multi-energy loads at the receiving end of the gas-electricity distribution network through various energy conversion devices.The travel strategy of EV users and the multi-energy demands of microgrids may cause the fluctuations of power flow of distribution networks,thus the independent planning methods for transportation and microgrids used in the traditional research may cause the voltage overlimit and the line overload.Therefore,the new power system with deep coupling between energy and transportation urgently needs a more comprehensive planning model to meet the safety and economic demands of various entities.To address the above issues,a collaborative planning model is proposed for the gas-electricity distribution network and transportation coupling system with the multi-microgrid integration.Considering the multi-energy complementary characteristics of microgrids,the collaborative planning model introduces a hydrogen energy system into the microgrid.By rationally configuring the microgrid energy conversion devices,the efficiency of gas to electricity within the microgrid is improved,thereby reducing the electricity demand of the microgrid and improving the operation safety of the gas-electricity distribution network.In the planning process,taking into account the privacy protection demands of various entities,a distributed solution framework is established to achieve decentralized and autonomous solution processes for each subsystem.Finally,the effectiveness of the proposed collaborative planning model and distributed solution strategy is verified based on the data from a certain location in Zhejiang Province,China.
