Can Clean Energy Policy Promote Environmental, Economic, And Social Sustainability?, Felix Mormann

Felix Mormann

Two and a half decades of clean energy policymaking focused primarily on environmental and economic sustainability have yielded considerable environmental and economic benefits. Along the way, however, other policy considerations, such as the social sustainability of the transition to a cleaner, renewably fueled energy economy, have gone largely overlooked. As clean energy technologies continue to gain ever-greater traction in the United States and global energy economies, the social impacts of their enabling policies become more and more salient. Already, ratepayers, taxpayers, and other stakeholders who fear being left behind by the clean energy transition question the “fairness” of today’s renewable …

Virtual Inertia: Current Trends And Future Directions, Ujjwol Tamraker, Dipesh Shrestha, Manisha Maharjan, Bishnu P. Bhattarai, Timothy M. Hansen, Reinaldo Tonkoski

The modern power system is progressing from a synchronous machine-based system towards an inverter-dominated system, with large-scale penetration of renewable energy sources (RESs) like wind and photovoltaics. RES units today represent a major share of the generation, and the traditional approach of integrating them as grid following units can lead to frequency instability. Many researchers have pointed towards using inverters with virtual inertia control algorithms so that they appear as synchronous generators to the grid, maintaining and enhancing system stability. This paper presents a literature review of the current state-of-the-art of virtual inertia implementation techniques, and explores potential research directions …

A Tale Of Three Markets: Comparing The Renewable Energy Experiences Of California, Texas, And Germany, Felix Mormann, Dan Reicher, Victor Hanna

Felix Mormann

The Obama administration has repeatedly identified the large-scale build-out of clean, renewable energy infrastructure as a key priority of the United States. The President’s calls for a cleaner energy economy are often accompanied by references to other industrialized countries such as Germany, hailed by many as a leader in renewable energy deployment. Indeed, the share of renewables in Germany’s electricity generation mix is twice that of the United States, and the ambitious “Energiewende” commits the country to meeting 80% of its electricity needs with renewables by 2050. While some praise the German renewables experience as successful proof of concept, others …
