Power flow algorithm for radial distribution system with voltage sensitive loads

This paper presents a novel method for evaluating Power flow in a radial distribution networks. Conventionally power flow algorithms used consider real and reactive power to be independent of node voltage which is not always true in case of distribution systems. Voltage sensitive nature of load imparts a considerable amount of influence over actual amount of power flowing in the system. A forward backward sweep based load flow technique that takes into consideration changes in amount of real and reactive power being consumed by loads is developed. Precise loss estimation based on newly developed power flow technique is performed.
