AGC, ISO, Bilateral Contracts, DPM, Restructured Power SystemAbstract
In this paper, the multi-units four-area automatic generation control is analysed in restructured power system. The conventional automatic generation control area with modifications is implemented for simulating automatic generation control (AGC) in restructured power system. A DISCO can contract individually and multilaterally with a GENCO for power and these transactions are done under the supervision of the ISO. In this paper, the concept of DISCO participation matrix is used to simulate the bilateral contracts in the four area simulation diagram. The calculated values of generators’ participation and tie-line power exchanges match with the corresponding actual values obtained by MATLAB-SIMULINK. Optimal transient responses are determined by substituting the optimal gains in the MATLAB-SIMULINK based four-area multi-units diagram.
