AGC of a multi-area multi-source hydrothermal power system interconnected via AC/DC parallel links under deregulated environment
We model AGC of a two-area multi-source restructured hydrothermal power system. Two-areas are interconnected via AC/DC parallel links under deregulated environment. Optimal control theory is applied to design PI structured AGC regulators. The system performance is compared with single-source restructured thermal system. Study is also extended to two-area non-reheat thermal system with GDB nonlinearity.
