This paper proposes an effective algorithm called chemical reaction optimization (CRO) in the field of power system to solve economic load dispatch (ELD) problems involving different equality and inequality constraints. Complex constraints like prohibited operating zone and ramp rate limit are also considered. System transmission loss has also been considered in the test system. Chemical Reaction...
The main objective of this paper is to allocate the reactive power load and loss of any power system network in presence of SVC with consideration of all reactive power resources present in the system. The contribution of each reactive power resources to cater a particular load has been calculated using proportional sharing technique. In addition to that an effort has been made to allocate the reactive...
In this paper a emission dispatch problem is solved to minimize the emission of oxides of nitrogen (NOx), considering both thermal generators and wind power source. Total overall cost of generation is taken as inequality constraint during the time of minimization of emission during optimization process. The effects of wind power to control overall NOx emission from thermal power plants are also investigated...
In this paper an effort is made to assess local and global voltage security of multi-bus power system in presence of STATCOM and SVC. A Global Voltage Security Indicator (GVSI) derived from series network equivalent of multi-bus power system has been employed to assess overall system voltage security. Thevenin's equivalent of the power system with respect to a particular load bus has been used to...
In this paper a unique methodology for assessment of voltage stability is proposed considering economic criteria using the concept of equivalencing the multi-bus system to a two bus radial system and by studying the necessary parameters of the equivalent system. Hence, a generalized global voltage stability indicator being developed, it has been applied to a typical 6-bus system and a practical 203-bus...
