Environmental Protection Power Dispatch for Modern Power System

Power Generation Dispatch Considering Energy Value and Environmental Protection

Electric power industry should play a bigger role in energy conservation and emission reduction, while the ecosystem degradation rises because of the shortage of energy, the greenhouse effect and the environmental pollution. Power generation dispatch is the key practice in electric power industry. In this paper, the value based dispatch theory is proposed, which assign the value of the natural ...

Application of Comparators in Modern Power System Protection and Control

This paper presents the two basic comparison techniquesThe amplitude and phase comparisons, used in power system protection and control. Phasor diagrams were used to discuss their relationships and circuit diagrams were modeled for the description of their operations. The general expression for impedance, Mho, positive offset and negative offset Mho characteristics were developed. At a stage si...

A New Multiobjective Evolutionary Algorithm for Environmental/Economic Power Dispatch

Abstrack In this paper, a new multiobjective evohrtionary algorithm for EnvironmentaUEconomic power Dispatch (EED) optimimtion problem is presented. The EED problem is formulated as a nonlinear constrainedmultiobjective optimization problem with both equatity and inequality constraints. A new Nondominated Sorting Genetic Atgorithm (NSGA) based approach is proposed to handle the problem as a tru...

Modern power system frequency response evaluation with virtual power plant penetration

New power systems based on VPP will be expanded in the future and analysis of the frequency behavior of these systems compared to current systems in the field of disruptions will be one of the most important issues of the system operators. In this paper, the equations of the frequency response model of conventional power system are expanded by considering the VPP's and their effective component...
