Open source alternative to GAMS/vSPDonline
However, this relies on having the propietary tool GAMS, which costs several thousand $ for a commercial license.Anyway, is there a way to run GDX files and SPD models using an open source alternative?This would be very beneficial to industry consumers. … Hi thereI am not aware of any open source option that can read and execute GAMS code.Some years ago, we tested open source solvers within GAMS and the performance wasn't great with vSPD.Phil … Also, we're not too far away from publishing a new version of vSPD that reads from a single (albeit quite large) daily GDX file, ie all SPD cases that result in a published dispatch price, which in turn goes into the final price on which each trading period is settled, will be packaged up as single daily GDX file.

Meter Register Content Codes - Impact on Billing
Should the customer be charged or credited for generation of energy injected into the network?Where an embedded generation (EG) register is presented with load flow, should the customer be charged or credited for generation volume? One of the issues I had to deal with as a trader was the inability to quote customers on sites where illegitimate register content codes are in place.It is not unreasonable for these issues to result in customers being charged for generation and credited for load consumption, whilst the market may receive generation volumes submitted as load. As at 31 July there were 26 IN24 registers on active ICPs across NZ. Tags: Metering, Registry, Register content code, MEP, EMI Electricity market information data statistics insights analytics
