Colonial differences in intercultural education: on interculturality in the Andes and the decolonization of intercultural dialogue

This article pushes for the possibility of alternative ways of thinking about the concept of interculturality depending on where and by whom it is being articulated (the geopolitics and body politic of knowledge). To illustrate this, the focus is shifted away from the policies of the European Union and UNESCO to the Andean region of Latin America where the notion of interculturalidad is not only a subject on the educational agenda but has also become a core component of indigenous social movements’ demands for decolonization. Part of the argument of this article is that interculturalidad, with its roots in the historical experience of colonialism and in the particular, rather than in assertions of universality, offers a perspective on interculturality that relies on other epistemologies. It concludes by arguing that interculturality should be seen as interepistemic rather than simply intercultural

Optimal Net-Load Balancing in Smart Grids with High PV Penetration

Mitigating Supply-Demand mismatch is critical for smooth power grid operation. Traditionally, load curtailment techniques such as Demand Response (DR) have been used for this purpose. However, these cannot be the only component of a net-load balancing framework for Smart Grids with high PV penetration. These grids can sometimes exhibit supply surplus causing over-voltages. Supply curtailment techniques such as Volt-Var Optimizations are complex and computationally expensive. This increases the complexity of net-load balancing systems used by the grid operator and limits their scalability. Recently new technologies have been developed that enable the rapid and selective connection of PV modules of an installation to the grid. Taking advantage of these advancements, we develop a unified optimal net-load balancing framework which performs both load and solar curtailment. We show that when the available curtailment values are discrete, this problem is NP-hard and develop bounded approximation algorithms for minimizing the curtailment cost. Our algorithms produce fast solutions, given the tight timing constraints required for grid operation. We also incorporate the notion of fairness to ensure that curtailment is evenly distributed among all the nodes. Finally, we develop an online algorithm which performs net-load balancing using only data available for the current interval. Using both theoretical analysis and practical evaluations, we show that our net-load balancing algorithms provide solutions which are close to optimal in a small amount of time.Comment: 11 pages.
