The ubiquity of synchronous generation should not be assumed in highly renewable power systems. Various problems may consequently arise: not least, the difficulties entailed in maintaining regional reactive power balance. Offering a potential solution to such problems, modern renewable generator technologies offer controllable reactive power resources. As many of these generators will be embedd...

One of EU’s actions against climate change is to meet 20% of our energy needs from renewable resources. Given that the renewable resources are becoming more economical to extract electricity from, this will result in that more and more distributed generation (DG) will be connected to power distribution. The increasing share of DG in the electricity networks implies both increased costs and bene...

This paper presents reliability evaluation techniques which are applied in distribution system planning studies and operation. Reliability of distribution systems is an important issue in power engineering for both utilities and customers. Reliability is a key issue in the design and operation of electric power distribution systems and load. Reliability evaluation of distribution systems has be...

In this study, the planning problem concerned with simultaneous placement of distribution generation (DG) and capacitor bank in the distribution network is investigated from a local distribution company’s (DISCO’s) viewpoint based on minimum total cost over the planning period and applying genetic algorithm (GA). The cost terms of the objective function include risk cost of load not supplied of...

In order to enable the single-pass design methodology, the planning of power distribution should be performed as early as possible. In this paper, we will tackle this problem at the floorplan stage. First, at the block level, we will present an effective method to model the behavior of local power network structure of a reused block. Next, at the full-chip level, we will present a floorplan-bas...
