Hello Dear, Regarding the problem formulationin MOST program, I have these questions that I am confused about.
1- Difference between zonal reserveand contingency reserve : I understand that zonal reserve are some constantamount of reserve specified before the solution, but what is the definition of"zone" and how can I specify zones? and what is the difference betweenzone and area in bus data? And what is the difference between zonal reserve andcontingency reserve? 2- Contingency reserves: what ismeant by it? and how can this reserve amount be determined or calculated? is its value determined after MOST solution or pre-specified? 3-Difference between contingencyreserve limits and physical ramping limits? 4- Difference between loadfollowing ramping (wear & tear) and load following ramp reserves? 5-Active contract value"Pc": what does it mean? (Is this a contract between consumers andutility or what?) and how its value be determined? (AfterMOST solution or the user specifies its value?) and what about the deviationsfrom it ? >From my reading on the manual andthe papers "Secure Planning and Operations of >Systems withStochastic Sources, Energy Storage, and Active Demand" & >"StochasticallyOptimized, Carbon-Reducing Dispatch of Storage, Generation, >andLoads", I understand that we have 2 stages, stage 1 determines thecontract >value and stage 2 determines the deviations from this value as arecourse >action. 6- Details about the cost functionsCp(P), CR(r), Cδ(δ)….. : the form of the equations,is it a quadratic or what type? And the coefficient needed to specify them? 7-Confusion about the usage ofprobabilities in the objective functions: ψα: probability of contingency used in cost of dispatch and redispatch functionf(p,p+,p-).(why it used in this cost function only?) ϒ: probability of making it toperiod 't' (what does "it" refer to here?) and why this probabilityused in all objective functions except the cost of dispatch & redispatch f(p,p+,p-)? 8-When using the DC network modelinstead of nonlinear network network the problem is converted from MINLP toMIQP, How does this happen? (Why not converted to MILP problem?) 9- What does "Nodal energyprices" mean? and what is the difference between it and "shadowprices" and "marginal prices"? 10- I understand that MOST is usedto model transmission systems and one can add wind and storage sources, but ifI want to model a Microgrid, how can I use MOST to model it? And what aboutadding PV generation? 11- What meant by transmissioncongestion and its effect on nodal energy prices, storage, and min up&downtimes? Sorry for elongation and waitingfor your appreciated answers Thanks in advance | | Virus-free. www.avg.com |
