摘要
能源互联网是以电力系统为核心,与天然气网络、热力网络等其他系统紧密耦合而成的复杂多能源网络,是能源与互联网深度融合的产物。为了满足需求方的负荷需求和多能源用能主张,为其选择最合适的能量路由方式,使能源经过最优路径传输至负载端。基于交易利润最大化的能量路由机制设计了能源广域网中园区间的多能源协同交易方式,提出了基于改进集中竞价的能源互联网多能源交易优化方法,为多园区间的能源交易寻找交易利润最大的经济最优路径。通过算例验证了所提优化方法的有效性。
The energy internet is a complex multi-energy network formed by the power system as the core,closely coupled with other systems such as natural gas networks and thermal networks,which is a product of the deep integration of energy and the Internet.In order to meet the demand side's load demand and multi-energy use proposition,choosing the most suitable energy routing method for the energy to be transmitted to the load side through the optimal path,this paper designs the energy WAN park in the energy wide area network based on the energy routing mechanism that maximizes transaction profits.The multi-energy collaborative trading method between the two countries,proposes an energy Internet multi-energy transaction optimization method based on improved centralized bidding,and finds the economically optimal path with the largest trading profit for energy transactions between multiple parks.Finally,an example is used to verify the effectiveness of the proposed optimization method.
