In this paper, a new active power loss allocation (LA) technique is proposed for allocation of network losses among its participants in a deregulated power environment. This method employs a forward‐backward sweep (FBS) based numerical technique for system load flow (LF) and power loss calculation with/without distributed generators (DGs). The complexity lying with the decomposition of cross‐term of power loss equation has been simplified mathematically, without any assumptions and approximations. The proposed LA establishes a direct relationship between two end voltages of a branch and its subsequent node currents in terms of node injected complex powers. It assigns losses to the end‐users with due consideration to their load demands and geographical locations. The penetration of DGs may increase/decrease loss of a power distribution network. In order to provide justice to the DG owners, this paper proposes a new DG remuneration technique, which assigns either incentives/penalties to the DG units after analyzing their exact impact toward network loss reduction/enhancement, without diverting any part toward the consumers' side compared to other established methods. The effectiveness of the proposed algorithm is investigated using a 33‐bus test system considering: various load levels, several DG capacities and different types of DG power injections. The results obtained highlight the efficiency and applicability of the present approach as compared to other established techniques.

基于前向后掠的数值方法求解分布式发电径向配电网的有功功率损耗

在本文中，提出了一种新的有功功率损耗分配（LA）技术，用于在解除管制的电源环境中在其参与者之间分配网络损耗。此方法采用基于前向后向扫描（FBS）的数值技术进行系统潮流（LF）和有/无分布式发电机（DG）的功率损耗计算。功率损耗方程交叉项分解的复杂性在数学上得到了简化，而无需任何假设和近似。提出的LA根据节点注入的复功率建立了分支的两个端电压与其后续节点电流之间的直接关系。它会根据最终用户的负载需求和地理位置将损失分配给最终用户。DG的渗透可能会增加/减少配电网络的损耗。为了向DG所有者提供公正，本文提出了一种新的DG薪酬技术，该技术在分析了DG单位对减少或增强网络损失的确切影响后，将其分配给了DG单位以鼓励/惩罚，而没有将任何部分转向消费者方面。与其他已建立的方法相比。使用33总线测试系统研究了所提出算法的有效性，该系统考虑：各种负载水平，几种DG容量和不同类型的DG功率注入。与其他已建立的技术相比，获得的结果突出了本方法的效率和适用性。它在分析了DG部门对减少或增强网络损失的确切影响后，将其分配给DG部门的奖励/惩罚措施，而与其他既定方法相比，没有将任何部分转移到消费者方面。使用33总线测试系统研究了所提出算法的有效性，该系统考虑：各种负载水平，几种DG容量和不同类型的DG功率注入。与其他已建立的技术相比，获得的结果突出了本方法的效率和适用性。它在分析了DG部门对减少或增强网络损失的确切影响后，将其分配给DG部门的奖励/惩罚措施，而与其他既定方法相比，没有将任何部分转移到消费者方面。使用33总线测试系统研究了所提出算法的有效性，该系统考虑：各种负载水平，几种DG容量和不同类型的DG功率注入。与其他已建立的技术相比，获得的结果突出了本方法的效率和适用性。
