International journal of electrical power and energy systems, 2015, Vol. 71, pp. 93-100This paper presents a conjectural-variation-based equilibrium model of a single-price electricity market. The main characteristic of the model is that the market equilibrium equations incorporate the effect of the voltage constraints on the companies’ strategic behavior. A two-stage optimization model is used to solve the market equilibrium. In the first stage, an equivalent optimization problem is used to compute the day-ahead market clearing process. In the second stage, some generation units have to modify their active and reactive power in order to meet the technical constraints of the transmission network. These generation changes are determined by computing an AC optimal power flow.
Additionality is a key requirement for the renewables based electricity to be used by electrolysers to produce renewable hydrogen. Additionality could be defined as the requirement that renewables-based electricity used [...]
China has always upheld multilateralism and has advocated the use of multilateral mechanisms to jointly address global climate change issues. This paper discusses what China does and why, and how [...]
Around 75% of European cargo transport operations in terms of ton-kilometers are performed by trucks, which, in turn, entail massive environmental and societal impacts. Prior to the COVID-19 pandemic, road [...]
