The Dynamic and Changing Development of EERA Networks

In this article the authors use two EERA networks as a case for a discussion on the development of research networks within the European Educational Research Association (EERA). They contend that EERA networks through their way of working create a European research space. As their case shows, the development of networks is diverse. The emergence of networks and the current group of thirty-one networks do not display a coherent and unified system. Thus they argue that EERA networks have to be studied as an open complex system in order to comprehend the multiplicity and creative and innovative space that these networks represent. They create a space for knowledge production in a European context, enabling educational researchers to see and experience their research in a more diverse setting.

The European Educational Research Association: people, practices and policy over the last 20 years

From a pragmatic point of view, it is the people who make an organisation, but organisations are both people and structures, and not least organisations develop culture. One of the significant features of the European Educational Research Association (EERA) as an organisation is that many of its activities are run by people on a voluntary basis. Apart from a small office, now in Berlin, which oversees and handles the everyday management, participation on Council, reviewing and programming for ECER (European Conference on Educational Research), managing networks, etc. are all undertaken as voluntary work by academics from across Europe (and beyond). From the large group of people who are currently sustaining these activities, many have participated from the beginning, but many others, after having been once at the conference, returned and got engaged in the work, for instance within one of the networks. Among the many who participate in EERA activities, there is a diversity of reasons for doing so, but there seems to be something which is recurring in what people say about why they do it. One of these recurring ideas is that the discursive norms of the organisation are enforced in the context of welcoming people and ideas, and second, there exists an intellectual generosity and egalitarianism which encourages newcomers to participate rather than protect themselves. We believe that this tells something about what EERA and ECER are about.

Avoided losses on LV networks as a result of microgeneration

In the scope of the discussions about microgeneration (and microgrids), the avoided electrical losses are often pointed out as an important value to be credited to those entities. Therefore, methods to assess the impact of microgeneration on losses must be developed in order to support the definition of a suitable regulatory framework for the economic integration of microgeneration on distribution networks. This paper presents an analytical method to quantify the value of avoided losses that microgeneration may produce on LV networks. Intervals of expected avoided losses are used to account for the variation of avoided losses due to the number, size and location of microgenerators, as well as for the kind of load distribution on LV networks.

Assessing the contribution of microgrids to the reliability of distribution networks

The emergence of microgeneration has recently lead to the concept of microgrid, a network of LV consumers and producers able to export electric energy in some circumstances and also to work in an isolated way in emergency situations. Research on the organization of microgrids, control devices, functionalities and other technical aspects is presently being carried out, in order to establish a consistent technical framework to support the concept. The successful development of the microgrid concept implies the definition of a suitable regulation for its integration on distribution systems. In order to define such a regulation, the identification of costs and benefits that microgrids may bring is a crucial task. Actually, this is the basis for a discussion about the way global costs could be divided among the different agents that benefit from the development of microgrids. Among other aspects, the effect of microgrids on the reliability of the distribution network has been pointed out as an important advantage, due to the ability of isolated operation in emergency situations. This paper identifies the situations where the existence of a microgrid may reduce the interruption rate and duration and thus improve the reliability indices of the distribution network. The relevant expressions necessary to quantify the reliability are presented. An illustrative example is included, where the global influence of the microgrid in the reliability is commented.
