ned (in terms of improvement to your objective) by changing the commitment variables to 0. I suspect that using non-zero PMIN values will clarify things. Ray On Sep 18, 2017, at 4:10 PM, Quarm JNR, Edward A <edwardarthur.quarm...@mavs.uta.edu<mailto:edwardarthur.quarm...@mavs.uta.edu

Zonal reserve with stochastic Wind generation in MOST

2017-09-21 Thread Quarm JNR, Edward A
Dear All, I am running a multi-period simulation with : 1. Zonal reserve requirement 2. Stochastic Wind generator 3. Load profile My output for reserve generation always includes an extra row for the wind generator but with zero output. For example, I have 5 generators in my

,ones(ng,1),1e-9*ones(ng,2)]; … and see if the results make more sense. This is due to the fact that the delta_+ and delta_- variables in (4.26) and (4.27) in the manual are only “tight” against these constraints if they have a positive cost on them. Ray On Sep 14, 2017, at 1:

Ramping constraints

2017-09-13 Thread Quarm JNR, Edward A
Hi community, I am running a multi-period simulation in MOST with the following constraints: 1. Zonal reserve requirement 2. Generator Minimum up time and down time I obtain output generation (P) but they violate ramp_30 on the last generator (which limits the period to period ramping).

MOST Results on Bus Voltage Angles

2017-08-31 Thread Quarm JNR, Edward A
Hi MATPOWER/MOST community, I am running a unit commitment simulation on MOST using a case study file for example "case3b" and I want to obtain bus voltage angles from the results that most gives. From my understanding. MOST uses DC network model to run a DCOPF with binary variables and
