Abstract: Now a day, the electrical network was restructured, to access power from any generator to any load. In real time, it is very difficult to make this type of transactions because of the transmission system constraints. Sometimes, the total active power losses may increase and finally system becomes unstable. Further, the cost of the total power losses should allocate either to the generators or loads. Normally, the voltage magnitude at generating plants was controlled but the voltage magnitude at load buses was not controlled. Hence it is always suggestible in analyzing the effect of loss allocations to loads. In this paper, a novel loss allocation strategy is proposed to allocate losses among the available loads. As the proposed methodology utilizes the process power flow tracing and increases the effectiveness of the problem solution. Numerical results are provided for the standard IEEE-5 bus, 30 bus and Indian-24 bus test systems with supporting validations using Bialek method.
