要約(日本語): It is generally known that using long-term contracts is a good way to mitigate market power. But there was a report that it is not always true, especially in electricity market with only a couple of buses and severe transmission constraints. A study using OPF is presented for studying the effects of long-term contracts on market equilibrium in electricity market with 3 or more buses. The result shows that long-term contracts may cause reduced social welfare in electricity market with 3 or more buses too.
