“…In particular, power-to-heat allows making better use of temporary renewable surplus generation. This may already apply (i) without the use of additional heat storage [67,40], particularly in case district heating systems can be used [33,29,45,46,66,70]. Utilization of renewable surpluses generally improves if (ii) additional active or passive heat storage is available [34,52,61,48,51,37,60,40,42,63,53,64], or if (iii) flexible fuel switching facilitated by hybrid heating systems enables "virtual" energy storage [59,47].…”

“…Some model analyses comprise additional features such as the provision of control power [30,46,33] and an explicit consideration of behavioral incentives for households [42]. Also here, implementing more markets or objectives could render a more detailed picture of the dual challenge of decarbonizing the energy sector(s) and providing the necessary flexibility.…”

“…Cost reductions are driven by (i) the substitution of fossil fuels [27,29,35,36,51,59,52,63,37], (ii) better use of capital invested in renewable assets by means of reduced curtailment [59,60,61,66,67,71,43], (iii) less need for costly auxiliary technologies such as peak-load capacity [29,40] or power storage [64], (iv) more efficient operation of thermal power plants because of less need for cycling and part-load operation [58,42], and (v) the use of existing district heating infrastructure [31,46,61,66,54,53]. With different co-authors, Hedegaard [27,29] simulates the Danish energy system with complementary models.…”

Flexible bioenergy supply for balancing fluctuating renewables in the heat and power sector—a review of technologies and concepts

et al. 2015

View full text Add to dashboard Cite

Today bioenergy plays a major role in the renewable energy provision, for heat and power and for liquid biofuels as well. With an increasing share of renewables on the one hand side and a limited availability of biomass on the other hand, the provision of bioenergy has to consider the demands of the future energy system with high shares of fluctuating wind and solar power. This includes new and improved technologies and concepts for biogas, biomethane, and liquid and solid biofuels, which are discussed in the following, while for the electricity sector, the demand for more flexible provision might take place in the years to come; for more flexible heat provision, the transition is expected in a longer time frame. For their market implementation adopted regulatory framework and price signals from electricity markets are necessary. Review

“…[20] uses a commercial software to model a CHP system which balances the variable wind generation while in [21] a model is proposed for optimizing the operation of a DH system with a solar thermal plant. In [22], a deterministic model is used to determine the provision of control power by a DH system. A unit commitment and power/heat dispatch model for CHP operation is used (but not presented) in [23] for wind power integration studies.…”

The integration of continuously varying and not easily predictable wind power generation is affecting the stability of the power system and leads to increasing demand for balancing services. In this study, a short-term operation model of a district heating system is proposed to optimally schedule the production of both heat and power in a system with high wind power penetration. The application of the model in a case study system shows the increased flexibility offered by the coordination of power generation, consumption and heat storage units which are available in district heating systems.
