Presence of distributed energy resources (DERs) in the case of proper planning can help to improve the technical and economic parameters of the system in distribution networks. In recent years, several algorithms and indices for optimal distributed generation planning with multiple objectives have been presented. In this paper, optimal placement and sizing of distributed generation sources with...

The electricity grid is the backbone of the power network and is at the focal point of technological innovations. Utilities need to introduce distributed intelligence into their existing infrastructure to make them more reliable, efficient, and capable of exploiting and integrating alternative sources of energy. The intelligent grid includes the infrastructure and technologies required to allow...

The fact that the electrical grid represents a critical and complex infrastructure has prevented it from experiencing major breakthroughs during decades. Therefore, some problems and inefficiencies have been carried around for a long while, up to the point that traditional electrical grid is far away from being prepared to face incoming challenges, such as properly integrating the foreseen high...

One of the key protection functionalities in the future active distribution networks will be reliable detection of islanding. Non-detection zone (NDZ) near a power balance situation and maloperation due to other network events have been the major challenges with traditional passive islanding detection methods like voltage, frequency, rate-ofchange-of-frequency, voltage vector shift (VVS). Howev...

Distributed energy resources (DERs) including distributed generators (DGs) and controllable loads (CLs) are managed in the form of several microgrids (MGs) in active distributions networks (ADNs) to meet the demand locally. On the other hand, some loads of distribution networks (DNs) can be supplied by retailers which participate in wholesale energy markets. Therefore, there are several decisio...

The focus of the European Union (EU) energy policy is on the promotion of low-carbon technologies and renewable-energy sources. In pursuit of this target, EU countries are setting up adequate support schemes (e.g. feed-in-tariffs). This is giving rise to different generation technologies and growing share of small scale generation in power networks. The paper deals with the impact of distribute...

With increasing availability of communication and control infrastructure at the distribution systems, it is expected that the distributed energy resources (DERs) will take an active part in future power systems operations. One of the main challenges associated with integration of DERs in grid planning and control is in estimating the available flexibility in a collection of (heterogeneous) DERs...

Abstract— Distributed energy resources systems are small power generation tools used to afford substitute solution or added enrichment of traditional electric power system. This paper is mainly concentrated on 1Ø multi-level inverter for Distributed Energy Resources. The objective of this paper is to reduce switches with increase in multi-level outputs which inherently reduces the cost & harmon...
