Friday, 13 March, 13:15-14:30 in M:IEA (seminar-room)

Seminar:

"Consumption management in the Nord Pool region: A Stability Analysis"

Erik Lindström, Mathematical Statistics, LTH

Description:
Integration of fluctuating renewables like wind and solar power is nowadays a hot topic, but this comes at a cost of decreased stability of the power system. The deterioration often translates into so-called spikes and drops in the electricity spot price, very large (even extreme) deviations from the regular spot price, followed by a reversion to roughly the original level a few days later. We use the spikes and drops as an strong indication that there is an imbalance in the physical power system in this paper. Independent SpikeModels (ISM) is a popular class of models for the electricity spot price that uses regime switching, typically having three regimes (base regime, spikes and drops). We fit a such model to Nord Pool spot data to characterize the size and intensity of these deviations, and proceed by augmenting the standard second generation, three factor Independent Spike Model by relating the spike and drop intensity to several factors and find strong statistical support for relating the consumption to the spike and drop intensity. The model is then used to quantitatively evaluate the effects when modifying the consumption in order to mimic how additional renewables are integrated into the power system or conversely the effects when smoothing consumption using strategies that can be implemented in smart grids. We use this tool to obtain a di28 rect measure of how much the spike and drop intensity can be reduced by smooth29 ing the consumption and see that even a small increase in the variability of the consumption translates into decreased stability (more spikes and/or drops) of the power system.


Monday 2 February @ 13 - 14 hr. in M:2112 (on the second floor in the M-building)

Master Thesis Presentation:

"High Precision Positioning and Very Low Velocity Control of a Permanent Magnet Synchronous Motor"

Patrik Önnheim, Dept. of Automatic Control, LTH, Lund University
Hampus Isaksson, IEA, LTH, Lund University

Description:
The purpose of this report is to evaluate a direct driven permanent magnet motor in high accuracy position and low speed operation. Actu- ation in this case is usually accomplished by stepping motors combined with belts and pulleys. High accuracy positioning is considered to be within 0.1 degrees and low speed 0.05 degrees per second. While at the same time have a 180 degree step response within 0.5 second. A model is derived of the motor along with methods for model param- eter identi cations. This model is the basis for simulation of the motor in closed loop control. A prototype is developed in order to prove the validity of the results made by simulations. Experiments on the proto- type resulted in two control methods, namely eld oriented control and synchronous control. Conclusions drawn from the projects are as follows. The simulations does mirror the inherent problems with the permanent magnet motor. The prototype developed for the project is functioning and highly capa- ble. Field oriented control was unable to meet the speci ed requirements. However combined with iterative learning control performance was im- proved signi cantly. Synchronous control satis ed most of the require- ments, although its responsiveness and low eciency are possible areas of improvement in future research.
