“…By definition, the residual load gives indications on periods of surplus or deficit of production of new RES. Accordingly, it has been the focus of many recent investigations evaluating the needed capacity of EES, of thermal storage and of additional dispatchable productions to help absorb large penetrations of new RES (Schill, 2014;Saarinen et al, 2015;Ueckerdt et al, 2015;Schweiger et al, 2017). In his analysis of negative price regimes, Nicolosi (2012) illustrated a connection between the residual load and the merit order.…”

How fast can one overcome the paradox of the energy transition? A physico-economic model for the European power grid

The paradox of the energy transition is that the low marginal costs of new renewable energy sources (RES) drag electricity prices down and discourage investments in flexible productions that are needed to compensate for the lack of dispatchability of the new RES. The energy transition thus discourages the investments that are required for its own harmonious expansion. To investigate how this paradox can be overcome, we argue that, under certain assumptions, future electricity prices are rather accurately modeled from the residual load obtained by subtracting non-flexible productions from the load. Armed with the resulting economic indicator, we investigate future revenues for European power plants with various degree of flexibility. We find that, if neither carbon taxes nor fuel prices change, flexible productions would be financially rewarded better and sooner if the energy transition proceeds faster but at more or less constant total production, i.e. by reducing the production of thermal power plants at the same rate as the RES production increases. Less flexible productions, on the other hand, would see their revenue grow more moderately. Our results indicate that a faster energy transition with a quicker withdrawal of thermal power plants would reward flexible productions faster.

Solar thermal and wind energy applications: Case study of a small Spanish village

The present work examines the supply of heating and electricity to the Spanish village of Uruena, using biomass and other local renewable sources as a result of the growing interest worldwide towards the development of sustainable and energy independent small communities. Specifically, this case study considers the design of a district heating system consisting of a solar heating plant, a biomass plant using straw as a sustainable fuel for the base load and an oil boiler for the peak load, coupled with a hot water tank as a thermal energy storage option. Two alternative scenarios are analyzed for electricity generation purposes, namely a system consisting of three small wind turbines and a system with a single large wind turbine. The results show that the cost of large-scale electricity storage depends on the application and often involves significant capital investments.

“…In addition, while an increasing influx of fluctuating renewable electricity production combined with a growing electricity demand from the transport and heating sector stresses the load-following capability of the electricity system, the very same technologies in a coordinated smart energy system approach can in fact help establish balances between production and demand and reduce problematic peak demands. Main technological solutions for this approach include wind power [4], [5], photovoltaic (PV) [6], [7], power-to-heat [8], [9], power-to-gas [10], [11] and battery technologies [12], [13].…”

Highlights-EnergyPLAN simulations of residential and communal batteries in combination with PV -Residential PV and battery set-up enables higher self-supply and customer involvement -Communal battery set-up leads to higher share of electricity fed to the grid -PV and batteries improve demand side management, balancing and production planning Abstract This paper presents an analysis of small consumers' involvement in smart island energy systems with a focus on the technical feasibility of photovoltaic (PV) systems in combination with batteries. Two approaches may be observed in the literature: the optimization on a household level with the aim of being self-reliant versus coordinated and collective technologies with increased integration across sectors and energy carriers. Thus, for household systems, the placement of a batterywhether aggregated or residentialcreates the basis for this investigation. The study is based on the case of the Danish island Samsø for which the two battery approaches are simulated using the energy system simulation model EnergyPLAN. Results indicate a tendency towards aggregated batteries being more favourable from a systems perspectivewhile on the other hand, residential batteries are more motivating and involving the consumers. The importance of minimizing flows to and from the grid as a result from fluctuating energy sources is addressed in both approaches. While residential batteries improve the individual household electricity supply, a communal battery would further regulate other inputs and demands. * Corresponding author [2]
