Due to the increased proportion of small renewable energy sources in a distributed setting (DG-RES), active control of small distributed energy producing and consuming systems will play an important role in future electricity grids [1]. These distributed energy resources have production patterns, which are either partially stochastic (e.g. wind, solar cells) or are coupled to the primary user process (e.g. co-generation of heat and electricity). Furthermore, on the demand-side, and increasingly on the electricity storage side, opportunities exist for actively serving stability applications in the grid by real-time supply/demand coordination. In the future, an information and communication layer for grid coordination could serve a portfolio of ICT-applications on timescales running from seconds to hours. To get a grip on these (r)evolutionary developments, possibly toppling the electricity grid, in this paper, architecture requirements for future high proportion DG-RES electricity grids are collected from a Power Electronics System point of view as well as from an ICT point of view using an inventory of business models in the power grid that focus on coordination of multiple small-scale DG-RES resources. Modeled from an ICT point-of-view, these give rise to architectures for applications that can successively be implemented in hardware and software as active components in the distribution grid. A number of possible grid control strategy coordination patterns (GCPs), which are defined in a generic, reusable manner, can be seen to emerge. GCPs, connected and intertwined to one another on several layers (physical, commercial) of the grid, together, can provide the framework for coordination in the overall intelligent grid. Bottom-up approaches of implementing coordination in future active grids appear to be the method of choice to use in implementing the GCPs. Software agents [2], [3] coordinating primary processes using market algorithms, as implemented in the PowerMatcher approach [3]-[4], appear to be very suited for this.

Advantages of liberalizing network sectors such as telecom, railway and electricity are said to be found in lower consumer prices, and more innovation in the sector. We assess the factors to innovation in the Dutch electricity sector with multiple interviews and a survey. One of the main conclusions is that in the institutional realm many factors are hampering and stimulating innovation. There is a lack of coherence of some current institutions and technological innovation. In order to improve innovation some important institutions should be altered or adapted.

AT the end of March 2007, the remaining quantity of recoverable gas reserves in the country has been in excess of 28.3 trillion cubic meters that is the second gas rich country in the word. While the geological studies in certain geographical regions of the country have not been thoroughly conducted yet. it is likely to explore further reserves of gas in the future. Therefore a thorough and explicit planning knowledge is essential for utilization of this energy carrier. Iran is one of the largest gas rich countries in the world that production potentials exceed gas injection and domestic consumption requirements. Gas can be utilized as feedstock for petrochemical and refining products or exported through pipelines or as LNG. By injecting gas into oil reservoirs while increasing the oil recovery ratio of oil fields, gas storage from production of shared reservoirs into non - shared reservoirs is as well accomplished. Gas consumption in domestic markets and its substitution with oil products in addition to environmental benefits, will also result into the optimum consumption of these products and relieve the government from the heavy burden of existing subsidies and the heavy expenditures of importing these products into the country. To supply gas requirements, proper operation and appropriate production of shared reservoirs such as south pars with the objective of securing gas requirements and providing balance of supply and demand as well as utilization of maximum share in these reservoirs are other essentials towards development of this vital industry. Several energy experts and Iran's economy analysts believe that further expansion and utilization of natural gas is an essential element for sustainable development and this energy carrier is considered the superior fuel of the 21 century. According to reliable estimations, natural gas in regard to its intrinsic characteristics and especially environmental suitability is one of the energy carriers that will attain the highest growth rate among other energy carriers with in the next two decades which itself is indicative for consumption growth of this substance in the global basket of energy consumption.

Managing large-scale transportation infrastructure projects is difficult due to frequent misinformation about the costs and benefits, which results in large cost overruns and benefit shortfalls that often threaten the project viability. This paper explores the explanations for cost overruns that have been presented in previous studies, and whether these explanations are theoretically embedded. Two categories of explanations for cost overruns are distinguished: political explanations and non-political explanations. This paper also investigates whether there are theories that have not yet been included in the literature on cost overruns that can contribute to the understanding of cost overruns. For political explanations agency theory is considered the most interesting and an eclectic theory is considered possible as well. Non-political explanations are diverse in character, therefore a range of different theories (including rational choice theory and prospect theory), dependent on the kind of explanation is considered more appropriate than one all-embracing theory.

In the last years, real-time railway traffic optimization experienced an increasing interest due to the expected growth of traffic and the limited possibilities of enhancing the infrastructure, which ask for a more efficient use of resources and the application of more advanced decision support tools. This paper presents a computerized train dispatching system, called ROMA (Railway traffic Optimization by Means of Alternative graphs), for supporting railway traffic controllers during operations. Innovative scheduling and rerouting algorithms have been developed in order to globally optimize disturbed railway traffic conditions. ROMA can anticipate the evolution of traffic, including the propagation of delays in a regional railway network, and can estimate the effects of different dispatching measures during a period of about 15 minutes ahead. Therefore, ROMA would enable traffic controllers to frequently perform incremental changes to the actual timetable to accommodate changes in traffic patterns due to disturbances, such as train delays and blocked tracks. An extensive computational study is carried out, based on a dispatching area of the Dutch railway network, to show the high potential of our train dispatching system as a support tool to improve punctuality.

Both scenario analysis and the adaptive approach are rarely used in transport infrastructure planning, while there seems to be a clear value in using them (given the massive uncertainties on both the supply and demand sides, and owing to the fact that infrastructure is typically a `slow and inert' component of the transport system). To assess why these techniques are rarely used, the authors carried out a study to determine whether these analytical approaches are (1) superfluous (that is, there is no great need for them in the policymaking sector) or (2) underused (that is, there appears to be a need for the approaches among policymakers, but the approaches are nevertheless not used), and why. The study focused on the Netherlands, a country where transport infrastructure investments (including their effectiveness and efficiency) have been high on the political agenda for decades.

In this paper, we study the cooperative observability conditions for the local observers formulated on large-scale power systems. A complex large-scale power system model can be considered as a union of several low-dimensional sub-systems where local observers are to implemented. Even if the large-scale system is observable, local observers formulated on such sub-systems may be unstable if the resulting local sub-systems are un-observable. The aggregated effect of the sub-systems, although, may lead to observability. Under certain assumptions, we show that the un-observable local sub-systems can lead to observability by allowing appropriate cooperation among the local observers. In particular, the local error covariances of the local observers can be assimilated such that they preserve a certain (approximated) structure of the global error covariance. This results into stable local observers for un-observable, but, cooperating sub-systems. We provide simulations to assert the findings in the paper.

Infrastructure projects are typically large, irreversible investments that deal with a rapidly changing environment. Flexibility could therefore be valuable for these projects. Valuation of flexibility is however not yet a part of standard evaluation toolkits. This paper reviews theoretical concepts, methodological issues and practical applications.

The depletion of energy resources, the quest for security-of-supply and the need to mitigate climate change may require or invoke for a transition of energy infrastructures. We conjecture that the phenomenon of transitions is not sufficiently understood to merit high expectations from transition management since energy infrastructures are complex, large scale socio-technical systems. Transitions are not only multi-layered phenomena; they include feedback loops within and across layers. We have combined four complementary approaches - Socio-technical regimes, social theory, Institutional Economics and Actor-Network theory - to unravel the phenomenon of transitions and present a functional specification of a transition modelling framework. We suggest the development of a hybrid modelling approach to enable the analysis of transitions of socio-technical systems, to provide support to decision-makers involved in shaping their transition and to explore the feasibility of transition management. System dynamics and agent-based modelling are suitable modelling paradigms using energy infrastructures as an example, as a first step towards enabling transition management.

Water provision has been and remains highly regulated because it is a "critical infrastructure" that requires tight coordination of its core transactions in order to maintain technical integrity as well as economic coherence in the system. If one looks at the history of developed countries, they all have had their water and sewerage systems developed mostly by public bureaus or, to a lesser degree, by private operators tightly supervised by public authorities. It is also noticeable that Public-Private Participation has become fashionable less because of failures in the running of water and sewerage systems in developed countries than because of constraints in public finances, particularly in developing countries. This is not to deny flaws and failures in many SOEs, but to temper their significance.The paper argues that we need looking at intermediate, "micro-institutions" that bridge the gap between institutional environment and organizational arrangements. Of course, these problems by far exceed the urban water sector.
