“…The fuel prices that are fed from the optimal contract sequence to the dispatch module, are real -as opposed to pseudo -fuel incremental prices. As Gibson et al pointed out[36], incremental prices, i.e., the price to pay for the next available unit of resources, are the appropriate prices fbr dispatch calculations. So, whereas updating the Lagrangian multipliers is the process to satisfy the problem constraints, updating the fiiel prices enforces an optimally ordered fiiel price schedule and…”
