In electrical power systems, unexpected outage of transmission sudden increase loads, the exit generators from service, and equipment failure, leads to a contingency occurring on one or several lines. The loads must be within specified state lines should not exceed thermal limits. One important methods used alleviate reduce congestion by injected Distributed Generation (DG) an optimal siting si...

application of distributed generation (dg) units in distribution networks has increased in recent years. sizing and sitting of dg units are two important factors which should be considered, especially for reduction of power losses in distribution system. this paper presents a new approach for dg placement in distribution systems using the mixed integer nonlinear programming (minlp). this approa...

Hybrid renewable energy systems (HRES) have been introduced to overcome intermittent nature of single-source renewable energy generation. In order to utilize HRES optimally, two issues must be considered: optimal sizing and optimal operation. The first issue has been considered vastly in several articles but the second one needs more attention and work. The performance of hybrid renewable energ...

Concern over global climate change as a result of fossil fuel use has resulted in energy production from renewable sources. Marine renewable energy devices provide clean electricity but can also cause physical disturbance to the local environment. There is a considerable paucity of ecological data at potential marine renewable energy sites that is needed to assess potential future impacts and a...

In this paper, we study the long-term power generation investment expansion planing problem under uncertainty. We propose a bilevel optimization model that includes an upper-level multistage stochastic expansion planning problem and a collection of lower-level economic dispatch problem. This model seeks for the optimal sizing and siting for both thermal and wind power units to be built to maxim...

With the rapid growth of wind energy development and increasing wind power penetration level, it will be a big challenge to operate the power system with high wind power penetration securely and reliably due to the inherent variability and uncertainty of wind power. With the flexible charging–discharging characteristics, Energy Storage System (ESS) is considered as an effective tool to enhance ...

The deployment of onshore wind power is an important means to mitigate climate change. However, turbines also produce local disamenities residents living next them, mainly due noise emissions and visual effects. Our paper analyzes how the presence affects socially optimal siting power. analysis builds on a spatial optimization model using geographical information system (GIS) data for Germany. ...

This research uses a comprehensive method to solve a combinatorial problem of distribution network expansion planning (DNEP) problem. The proposed multi-objective scheme aims to improve power system's accountability and system performance parameters, simultaneously, in the lowest possible costs. The dynamic programming approach is implemented in order to find the optimal sizing, siting and timi...
