摘要
利用电路基本理论,从注入功率分解的角度出发,对电网功率的分布进行分析,得到了多电源电流分量在电网络任意节点和支路构成功率的解析表达式,明确了功率交叉项的来源;提出功率分量各自按照网络独立分布的理论,形成了一种新的潮流追踪算法,并用算例验证了该方法的合理性。
Up to now, the problems arising from the nonlinear coupling of power have not been solved. This paper analyses the characteristic of power distribution from the angle of power injection allocation, using the classical circuit theory, and obtains the analytic expression of source current component on multi-source network in random node and branch. It also specifies the source of cross items in power components. The methodology proposes that component of the power distributes independently to one another only according to network structure. Finally the validity and feasibility of the method is demonstrated using the IEEE 9 bus system.
