分布式电源（DG）的并网对配网的运行和安全具有很大的影响。在分析常见DG模型基础上，提出一种改进前推回代算法，考虑到该算法中PV节点处理能力较差，引入无功修正，同时分析DG并网对系统的影响。在IEEE33节点系统中进行可行性验证，结果表明，分布式电源的接入对系统电压和网损有影响，一定程度的无功注入会降低网损。
分佈式電源（DG）的併網對配網的運行和安全具有很大的影響。在分析常見DG模型基礎上，提齣一種改進前推迴代算法，攷慮到該算法中PV節點處理能力較差，引入無功脩正，同時分析DG併網對繫統的影響。在IEEE33節點繫統中進行可行性驗證，結果錶明，分佈式電源的接入對繫統電壓和網損有影響，一定程度的無功註入會降低網損。

The parallel operation of distributed generation (DG) has big influences on the safety and operation of distribution power net-work. The article raises improved forward and backward substitution method based on the analysis of the general DG model. With the consideration of poor ability of PV nodes treatment in the method, the reactive power correction is used; meanwhile it also analyzes the influences of DG interconnection to the system. With the process of verified feasibility in IEEE33 nodes system, the result comes out that the access of DG has influences on system voltage and power loss, the injection of a certain amount reactive power will reduce pow-er loss.
