    Abstract

    This paper proposes a new method to allocate real power and real power loss of individual generators to system loads. Both allocation procedures are conducted independently and it is based on current operating point of the system, computed through AC load flow program. Based on solved load flow results, the method partitions the Y-bus matrix to decompose the current of the load buses as a function of the generators' current and load voltage. Then it uses the modified admittance matrix to decompose the load voltage dependent terms into components of generator dependent terms. Finally using these two decompositions of current and voltage terms, the real power transfer between loads and generators are obtained. Similarly, by using the same concept, real power loss allocations caused by generators and loads are discussed and cost of real power loss due to generators and loads is carried out in this study. The advantage of the proposed methodology is demonstrated by using a simple 5-bus system and the modified IEEE 24-bus RTS system. The proposed methodology provides better reliability and minimizes the limitations of conventional power flow tracing methods.
