Greenpeace releases Smart Energy Access Report for Bihar, India
Langen, Germany (May 2012)
Together with Greenpeace, energynautics has investigated the potential role of microgrids in rural electrification. The microgrid approach is attractive because it can facilitate the integration of renewable energies, thereby contributing to national renewable energy targets. Being built from modular distributed generation units, it can adequately adjust to demand growth. In addition, it can operate both in island mode and grid-connected mode, making operation flexible and can also offer grid support features.
This report demonstrates with a case study how this bottom-up approach with microgrids would work. It focuses on development in the state of Bihar in India.

Report for AEMO Wind Integration Investigation published
Australia, December 06, 2011
Commissioned by the Australian Energy Market Operator (AEMO), energynautics prepared a report which reviews wind integration studies conducted around the world. The report provides a summary of the experiences in terms of the key technical issues studied, the methodologies and assumptions used, and main conclusions of the investigations, with a focus on island operation of power systems, and with high penetration of variable renewable energy generation. Aspects that are relevant to the NEM were identified in conjunction with AEMO, and suggestions on how AEMO could prepare comprehensive wind power integration studies for the expected level of renewable energy development in the future were made. These findings are also presented in this public report.

Dr. Eckehard Tröster on Powergrid Europe 2010 in Amsterdam
Amsterdam (9th June 2010)
Dr. Eckehard Tröster presents the results of the fault ride through study of gas-engine CHPs commissioned by VDMA on Powergrid Europe in Amsterdam.
The presentation can be downloaded here: FRT Study Powergrid 2010 Amsterdam (PDF | 1,1 MB)
Presentation of the Fault-Ride-Through Study at the network technology/network operation forum in the VDE (FNN)
Langen, Germany (April 2010)
According to the new medium voltage grid codes in Germany, generating plants
must stay connected during a short-circuit fault in the grid. Due to their low
inertia and the difficulties in shutting off the gas supply abruptly, gas-engine
gen-sets accelerate during a fault and cause the generator to fall out of step
with the grid frequency, decoupling it from the grid.
Commissioned by VDMA, energynautics has studied different solutions to this problem, such as increasing inertia, using a braking resistor or eddy-current brake, or a full power converter to improve the fault-ride-through behaviour of the gen-set in order to stay safely connected to the grid.
Investigations have been carried out using the software tool DIgSILENT PowerFactory and were based on the data of five gen-sets in the range of 220 kW up to 6.9 MW.
The study gave valuable insights for the discussion between the grid operators and the gen-set manufacturers.
