Size Optimization of New Hybrid Stand-alone Renewable Energy System Considering a Reliability Index
Over last two decades, solar and wind energies have
become an alternative to traditional energy sources. These
alternative energy sources are non-polluting, free in their
availability and are renewable. ...
Coordination of Overcurrent and Distance Relays Using Hybrid Particle Swarm Optimization
Protection of power transmission has an important role in power systems. To have a better protection it is common to
combine difference types of relays, which combination of overcurrent and distance relays is a ...
Optimal Coordination of Overcurrent and Distance Relays with Hybrid Genetic Algorithm
To achieve better protection, it is common to use both
distance and overcurrent relays as main and backup relays
respectively, in power transmission protection scheme. In this
situation it is necessary ...
Size Optimization of New Hybrid Stand-alone Renewable Energy System Considering the Reliability Index
Nowadays, political and economic crisis, limitation of fossil reserves, environmental concerns, population growth and economic growth resulted in an increase in the use of renewable energy resources. However, the main ...
Optimal Sizing of Hybrid Wind/Photovoltaic/Battery Considering the Uncertainty of Wind and Photovoltaic Power Using Monte Carlo
Using hybrid renewable energy is one of the best alternatives to supply the electrical energy at remote areas. Renewable energy sources are depended to weather conditions or other factors, so for supplying load with renewable ...
Effect of Increasing the Grounding Grid Resistance of a Ground System at a Substation on the Safety and Transient Overvoltage on the Interior Equipments
In substations, protective equipments such as arresters
and neutral transformer are being connected to substation
ground grid to protect them against transient overvoltage, firing
and other damages. ...
