2. How does falling incumbent profitability affect energy policy discourse? : The discursive construction of nuclear phaseouts and insufficient capacity as a threat in Sweden

- Abstract
What happens to energy policy discourse when falling profitability makes it difficult to frame incumbent technologies as necessary for providing affordable energy? And how does this affect energy policy? This article investigates how Swedish energy policy discourse responded to a profitability crisis that struck its incumbent nuclear regime in 2016, and how a political decision to support nuclear power was legitimized. It uses Carol Bacchi’s Foucault-inspired policy analysis to analyse 13 interviews and 31 policy documents, and shows how the crisis was met with the framing of nuclear power as a “plannable” energy source (in contrast with intermittent renewables) that was necessary for ensuring capacity adequacy, and with the construction of an ultimatum: to remove a tax on nuclear power or to see nuclear power phased out so abruptly that the power system would be jeopardized. It explores the discursive and institutional conditions that enabled this framing, argues that similar discourses are likely to be constructed in other contexts where capacity adequacy is a more pressing impediment to energy transitions than in Sweden, and points out that energy research risks reproducing dominant discourses by overstating the merits of incumbent baseload technologies.

A novel renewable energy intermittency model and a new midterm dynamic simulation tool in power systems are developed for examining dynamic behavior along the load curve for different combinations of the system operation reserves and renewable portfolio standard (RPS) rates. The system's import limits are considered. It is concluded that ignoring intermittency and governor effects is an inadequate method to assess intermittency impact. The intermittency midterm dynamic impact must be studied. For the studied system, the instability is expected to be about 25 % RPS with current reserves. Besides, the most vulnerable peak hour to instability is the afternoon peak hour when solar begins to drop off. This article stimulates further dynamic intermittency studies on the issues caused by renewable intermittency. The studies on the issues caused by renewable intermittency have not been revealed because of inadequate/incomprehensive study methodologies so that effective, mitigative solutions can be developed to guarantee the reliability of power grid when incorporating higher RPS if high operation reserves are impractical.

An optimal energy management is addressed in the residential building. The residential building is equipped with renewable energies including wind turbines and solar panels. The uncertainty of renewable energies is modeled by stochastic programming. The demand response program is simultaneously adopted to handle such uncertainty and reducing the energy cost. In this respect, four different loads are modeled in the building including interruptible, constant energy, constant power, and uninterruptible loads. The aforementioned loads are properly adjusted and dispatched for minimizing the energy cost as well as to deal with renewable energy intermittency. The bidirectional operation is modeled for the building and it can send energy to the grid or receive it from the upstream network. The results verify that the introduced model can efficiently harvest all possible energy of the wind-solar system, handle the uncertainty, minimize the cost, and operate as off-grid. All of these purposes are achieved by optimal dispatching and adjusting of the loads through the proposed demand response program. 2019 Elsevier Ltd Scopus 2-s2.0-85076009468
