Abstract

The future grid encourages distributed energy resources (DER) integration with main power grid to mitigate with the problems of demand-supply mismatch. However for real-time monitoring of voltage profile and line flows it is necessary to continuously run the load flow. However, distribution network (DN) suffers from non-convergence of conventional load flow method (Newton-Raphson) because of high WX ratio. This has motivated to develop a better load flow solution method which will help to address the above mentioned issues with proper allocation of DER for performance enhancement of three-phase unbalance DN. The paper proposes modified forward/backward sweep (FBS) method which helps to identify the weak nodes in network violating the given operating constraints and recommends to implement DERs on such weak nodes to improve voltage profile and reduce stress on power system network. The two-fold contribution of the paper in development of method and performance enhancement is validated using standard IEEE 34 bus which confirms the effectiveness of DERs insertion for three-phase unbalance DN.

用DER增强三相不平衡配电网的性能

未来电网鼓励分布式能源与主电网的整合，以缓解供需不匹配的问题。然而，为了实时监测电压分布和线路潮流，需要连续运行负荷潮流。然而，配电网由于WX比较高，存在传统潮流法(牛顿-拉夫森法)不收敛的问题。这促使开发一种更好的负载流解决方法，这将有助于解决上述问题，适当分配DER以增强三相不平衡DN的性能。本文提出了改进的前向/后向扫描(FBS)方法，该方法可以识别出网络中违反给定运行约束的弱节点，并建议对这些弱节点实施DERs，以改善电压分布，减轻电网压力。采用标准IEEE 34总线验证了本文在方法开发和性能增强方面的双重贡献，证实了三相不平衡DN中der插入的有效性。
