In Germany, the ongoing expansion of decentral renewable energy sources (RES) is decreasing the full load hours of traditional power plants and consequently their profitability. In the medium and long-term this could result in a crowding out of conventional, regionally concentrated power plants. This poses increasing substantial challenges to a reliable operation of power systems. Due to the ambitious...
This paper presents a two-stage optimisation approach to regional energy planning with biomass utilisation. The aim of the first stage is to determine the optimal energy mix and the bioenergy target, which is to be fulfilled in the second stage when synthesising the optimal biomass supply chain network. The mathematical formulation of the two stages yields two linear models, for which global optimality...
The energy internet paradigm provides a platform to integrate and utilize multiple energy resources through advanced hardware interfaces, communication infrastructure and operational intelligence. In this paper, a robust energy management framework is proposed for dispatching multiple renewable energy resources including solar power, wind power and biomass generation, and flexible loads. In the framework,...
With increasing amounts of power generation from intermittent sources like wind and solar, capacity planning has not only to account for the expected load variations but also for the stochastics of volatile power feed-in. Moreover investments in power generation are no longer centrally planned in deregulated power markets but rather decided on competitive grounds by individual power companies. This...
