Load following in a bilateral market with local controllers

In this paper, the conventional Automatic Generation Control (AGC) of two-area interconnected power system is modified to take into account the effect of bilateral contracts between the supplier and customer. A load following controller on each generator involved in the bilateral contract is considered. A separate control scheme for generators taking part in load-following is proposed to share the uncontracted power demanded by some customers. Simulation studies show that both the control schemes are very effective for the generators taking part in load following.

► AGC involving bilateral contracts in deregulated power markets have been studied.
► Effect of load following controller on each generator in bilateral contract has been investigated.
► A new control scheme is proposed so that a generator in load following can also share uncontracted power demand.
