@@ -24,8 +24,8 @@ Returns a dictionary mapping `(bus_name, time)` to the marginal price.
WARNING: This approximation method is not fully developed. The implementation is based on MISO Phase I only.
1. It only supports Fast Start resources. More specifically, the minimum up/down time has to be zero.
2. The method does NOT support time series of start-up costs.
3. The method can only calculate for the first time slot if allow_offline_participation=false.
2. The method does NOT support time-varying start-up costs.
3. AELMPs are only calculated for the first time period if offline participation is not allowed.
