“…(Dena, 2008), which o ers an upside potential for the prices of grid services that few market participants are able to o er (e.g., positive reserve power). At the same time, other services (especially negative reserve power) could also be provided by wind farms or large eets of electric vehicles (Andersson et al, 2010), which might put the prices under pressure.…”

Motivated by an ever increasing share of intermittent renewable generation, a variety of energy players considers new projects, which could increase the available capacity by up to 60% until the end of the decade. This paper analyzes the current development and evaluates the revenue potential as well as possible barriers. Overall, the prospects for new pumped-hydro storage plants have improved, even though profitability remains a major challenge.

“…The cycle stability Z is a quantity which depends on a large number of parameters such as C-rate, DOD, temperature, humidity and time and which strongly varies among different battery chemistries [18]. It is therefore not possible to reliably model the cyclic lifetime so that many studies simply assume a fixed number for Z [7,9,11,12]. To at least account for the important dependency of battery lifetime from the DOD, calculations in this paper are based on a functional relation between Z and DOD.…”

“…In case an EV would be upgraded specifically for the purpose of providing higher V2G power, the related costs would, however, have to be explicitly taken into account as fixed costs in Eq. (12). As this investment would be in the range of several thousand S$, it is assumed that such an upgrade would not be performed specifically for V2G.…”

A charging and dispatching strategy for optimizing profits from V2G is presented. This optimization strategy builds on temporally resolved electricity market data. A case study shows that this method turns a S$ 1000 annual loss into a S$ 130 profit. Sensitivity analyses indicate potential for further increase of profitability. Employing this strategy in other countries is assumed to yield much greater profits. a r t i c l e i n f o b s t r a c tEmploying electric vehicles as short-term energy storage could improve power system stability and at the same time create a new income source for vehicle owners. In this paper, the economic viability of this concept referred to as Vehicle-to-Grid is investigated. For this purpose, a price-responsive charging and dispatching strategy built upon temporally resolved electricity market data is presented. This concept allows vehicle owners to maximize returns by restricting market participation to profitable time periods. As a case study, this strategy is then applied using the example of Singapore. It is shown that an annual loss of S$ 1000 resulting from a non-price-responsive strategy as employed in previous works can be turned into a S$ 130 profit by applying the price-responsive approach. In addition to this scenario, realistic mobility patterns which restrict the temporal availability of vehicles are considered. In this case, profits in the range of S$ 21eS$ 121 are achievable. Returns in this order of magnitude are not expected to make Vehicle-to-Grid a viable business case, sensitivity analyses, however, show that improved technical parameters could increase profitability. It is further assumed that employing the priceresponsive strategy to other national markets may yield significantly greater returns.

“…The cars' owners want to maximize the usage of their resources and earn extra money with the cars when they are not in movement. They can do that by participating in the frequency control market, where electric car capacity is aggregated and sold as a resource to the transmission system operator [28]. In our scenario, the electric vehicle (EV) aggregator operates charging stations, where cars should be plugged in to the grid when idle.…”

Abstract. In the design phase of business collaboration, it is desirable to be able to predict the profitability of the business-to-be. Therefore, techniques to assess qualities such as costs, revenues, risks, and profitability have been previously proposed. However, they do not allow the modeler to properly manage uncertainty with respect to the design of the considered business collaboration. In many real collaboration projects today, uncertainty regarding the business' present or future characteristics is so significant that ignoring it becomes problematic. In this paper, we propose an approach based on the Predictive, Probabilistic Architecture Modeling Framework (P 2 AMF), capable of advanced and probabilistically sound reasoning about profitability risks. The P 2 AMF-based approach for profitability risk prediction is also based on the e 3 -value modeling language and on the Object Constraint Language (OCL). The paper introduces the prediction and modeling approach, and a supporting software tool. The use of the approach is illustrated by means of a case.
