Real and Reactive Power Transfer Allocation Utilizing Modified Nodal Equations

Hussain Shareef
This paper proposes a new method to identify the real and reactive power transfer between generators and load using modified nodal equations. Based on available 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 voltages. Then, it uses the modified admittance matrix to decompose the load voltage-dependent term into components of generator dependent terms. By using these two decompositions of current and voltage terms, the real and reactive power transfer between loads and generators are obtained. The effectiveness of the proposed method is demonstrated by using a simple 5-bus system and the modified IEEE 30-bus system. The proposed methodology provides reasonable and acceptable results to real and reactive power transfer allocation.
