摘要:

本文研究了混合电压和电流源电路拓扑对电力依赖性的影响。证明了任何稳态直流电路的功率依赖于一组关键变量,即基本节点电压和基本边电流。每个稳态直流电路均可分解为电压控制子电路和电流控制子电路。在这样的分解下,混合源电路的I²R损耗始终是两个子电路损耗之和。本文最后表明,混合源电路的总功率可通过上述关键电压和电流变量表达的功率的临界点来确定。讨论了其与电网操作拓扑控制的可能关系。

英文摘要:

The way in which electric power depends on the topology of circuits with mixed voltage and current sources is examined. The power flowing in any steady-state DC circuit is shown to depend on a minimal set of key variables called fundamental node voltages and fundamental edge currents. Every steady-state DC circuit can be decomposed into a voltage controlled subcircuit and a current controlled subcircuit. In terms of such a decomposition, the I^2R losses of a mixed source circuit are always the sum of losses on the voltage controlled subcircuit and the current controlled subcircuit. The paper concludes by showing that the total power flowing in a mixed source circuit can be found as critical points of the power expressed in terms of the key voltage and current variables mentioned above. The possible relationship to topology control of electric grid operations is discussed.
