abstract nowadaysphotovoltaic solar cells (pvs) areacknowledged the fastest growing energy technology in the word, however, they only account for only fraction of current global renewable energy capacity. it isrecognized that this incomplete market penetration has been largely a result of the technology’sexcessive cost. so researchers are trying to find innovative, economic way with theaim of ...
In the present study, investigated an energy production system using three types of renewable energy: solar, wind and ocean thermal energy with climatic conditions and close to areas with high potential for the OTEC system, Has a good position in terms of wind speed and solar radiation, used them as energy sources. The proposed system is designed and evaluated based on the total daily electrici...
This research addresses distributed proportional power sharing of inverter-based Distributed Generators (DGs) in microgrids under variations maximum capacity DGs. A microgrid can include renewable energy resources such as wind turbines, solar panels, fuel cells, etc. The intermittent nature causes their capacities. Since DGs be regarded Multi-Agent-Systems (MASs), a consensus algorithm is desig...
Utilizing distributed generations (DGs) near load points has introduced the concept of microgrid. However, stochastic nature of wind and solar power generation as well as electricity load makes it necessary to utilize an energy management system (EMS) to manage hourly power of microgrid and optimally supply the demand. As a result, this paper utilizes demand response program (DRP) and battery t...
Although fossil fuels consumption may causes to rapid economic growth, but due to related pollutants and its consequences, the world has suffered from climate changes. Moreover, fossil fuel resources such as petroleum, gas, coal and uranium are being exhausted rapidly in the last decades. Therefore, seeking an appropriate as well as low-cost alternative for the above-mentioned energy carriers i...
This paper has developed a novel multiobjective function for optimal sizing and sitting of Distributed Generation (DG) units and capacitor banks in simultaneous mode to improve reliability and reduce energy losses. The proposed function consists of four objectives: Cost of Energy Not Supplied (CENS), System Average Interruption Duration Index (SAIDI), costs of energy loss and investment. A nove...
abstract: enviromental concerns, improvements in renewable energy technologies, governmental incentives for the use of these resources, and increased t&d; costs, are the main factors driving the energy sector into a new era, where considerable portions of electrical demand will be met through widespread installation of distributed energy resources (ders). the virtual power plant (vpp) is a dece...
Abstract: In the last decade, the amount of distributed generation connected to the distribution network is increasing. The presence of distributed generation resources in distribution systems has a great influence on its behavior and it is necessary to consider the impact of these resources on the distribution network design. In this study, Optimal Coordinated Voltage Control (OCVC) using wind...
[1] It took the solar polar passage of Ulysses in the early 1990s to establish the global structure of the solar wind speed during solar minimum. However, it remains unclear if the solar wind is composed of two distinct populations of solar wind from different sources (e.g., closed loops which open up to produce the slow solar wind) or if the fast and slow solar wind rely on the superradial exp...
