Simulated Annealing Based Coordinated Wind-Thermal Unit Commitment


     

   Subscribe/Renew Journal


Efficient and optimum economic operation and planning of electric power generation system have occupied important position in electric power industry. The dependability of thermal power alone results in emission of polluting gases and depletion of conventional sources. This increased the interests in integrating renewable energy sources like wind, tidal, geothermal etc. into existing thermal power system. Due to the development in the field of power electronics and other allied technologies wind is preferred. For such coordinated systems, utilization of wind along with thermal results in alteration of reliability criteria owing to the intermittency and unpredictability of wind power generation. This paper deals with integrating wind energy with an existing thermal power system using Simulated Annealing (SA) Algorithm along with Constrained Dynamic Economic Dispatch (CDED) method. CDED is used to calculate wind power to be integrated to the existing system obtained by intermixing thermal and wind constraints. SA algorithm is used for optimizing. Simulation result shows the effect of wind power generation in reducing total fuel cost.

Abstract


Efficient and optimum economic operation and planning of electric power generation system have occupied important position in electric power industry. The dependability of thermal power alone results in emission of polluting gases and depletion of conventional sources. This increased the interests in integrating renewable energy sources like wind, tidal, geothermal etc. into existing thermal power system. Due to the development in the field of power electronics and other allied technologies wind is preferred. For such coordinated systems, utilization of wind along with thermal results in alteration of reliability criteria owing to the intermittency and unpredictability of wind power generation. This paper deals with integrating wind energy with an existing thermal power system using Simulated Annealing (SA) Algorithm along with Constrained Dynamic Economic Dispatch (CDED) method. CDED is used to calculate wind power to be integrated to the existing system obtained by intermixing thermal and wind constraints. SA algorithm is used for optimizing. Simulation result shows the effect of wind power generation in reducing total fuel cost.
