GAMS IN SYSTEM ELECTRICITY IEEE 118 BUS

In the deregulated electricity Pool Market the pool operator computes, through an optimal power flow program, the nodal prices for each bus of the system. This is the price of power, which the suppliers are paid, and the price, which the consumers are billed. In order to calculate these prices the pool operator receives bids curves from the market participants (Fig. 2)
