This article uses dynamic panel data analysis to examine the impacts of regulatory reforms in the electricity sector. We find that short term negative effects of ownership unbundling are approximately cancelled out by later positive impacts. Third party access seems to allow taking the benefits but avoiding the costs of ownership unbundling. The implementation of electricity exchanges has a positive...
In this paper the costs of integrating fluctuating sources like wind or solar into an existing electricity system are quantified using a systematic, theoretically well-founded approach. The paper notably stresses that this requires to measure integration costs against some reference technology and it highlights the link between integration costs and changes in system costs. The costs related to wind...
In this situation the operation and management of power systems with high shares of wind power require extended analyses. This panel fits very well with the objectives of IEA annex 25 on design and operation of power systems with large amounts of wind power.
In most electricity markets, a key restriction for portfolio optimization is the limited liquidity. Hence, standard models for decision problems have to be adapted to cope with this situation. This paper shows an approach dealing with this situation by including a liquidity function into the standard mean- variance model going back to Markowitz. This leads to a quadratic optimization problem which...
