question regarding negative price in electricity #872

Hi everyone, I want to know if GenX can simulate the negative price policy. I tried to look at it but only find that the excess energy will just be curtailed. thank you |

GenX produces locational marginal prices for each model zone as the dual of the electricity demand balance constraint for each region. These values can be negative, when either a thermal power plant with unit commitment could avoid a costly shut-down/start-up operation if demand were higher, or if production subsidies or energy share requirements for various resources are included (in which case curtailment of these resources would have an opportunity cost reflected in the negative price). So if you are trying to simulate negative pricing from e.g. a production tax credit or renewable portfolio standard, GenX can do that. Does that answer your question? If not, please add further context on what you are hoping to do, and we can try to help. |
