Distributed Tertiary Control of DC Microgrid Clusters
IEEE Transactions on Power Electronics, 2016A distributed control method is proposed to handle power sharing among a cluster of dc microgrids. The hierarchical control structure of microgrids includes primary, secondary, and tertiary levels. While the load sharing among the sources within a dc microgrid is managed through primary and secondary controllers, a tertiary control level is required to

Load shifting for tertiary control power provision
2015 IEEE 5th International Conference on Power Engineering, Energy and Electrical Drives (POWERENG), 2015The objective of this work is load shifting of domestic appliances for tertiary reserve provision. Aggregate load curve simulators are built by modelling stochastic consumer behaviour. Analysis is then performed on the number of loads that are required to aggregate in order to provide 5MW tertiary control power to participate in the Swiss ancillary ...

MPC-based tertiary and secondary optimal control in islanded microgrids
2015 IEEE International Symposium on Systems Engineering (ISSE), 2015Microgrids that are able to work both in grid-connected and islanded modes need a hierarchical structure based on tertiary, secondary and primary controllers, which are fundamental for the maintenance of frequency and stability. In this paper, two types of controllers are formalized and solved as optimal control problems: tertiary and secondary ...

Palaeohydrogeology and Water Quality Control of the Tertiary Aquifer, Kuwait
Water International, 2007Abstract The State of Kuwait is located at the northwestern corner of the Arabian Gulf and covers an area of about ≈18,000 km2. The aquifer under investigation is the Eocene Dammam limestone aquifer. This paper discusses the hydrochemistry of the aquifer through the period 1972–2002 in order to identify the chemical and genetic types of groundwater ...

New Water-Based Muds for Tertiary Shale Control
SPE Drilling Engineering, 1992Summary This paper describes laboratory and field assessments of a series of inhibitive water muds developed by BP. RCS 1 contains cationic starch to control fluid loss and to inhibit shale expansion further. RCS 2 is a highly inhibitive version of RCS 1 containing polyglycerol.

Astronomically controlled cycles in the lower Tertiary of Gubbio (Italy)
Earth and Planetary Science Letters, 1987Abstract A grouping of marl limestone beds in the Tertiary of Gubbio is interpreted in terms of sedimentary cycles. Two methods of recording are used: subjective mapping of cycle boundaries in the field and power spectral analysis of bed thickness measurements. Both result in cycle thicknesses of between 30 and 70 cm.
