  3. 3. INTRODUCTION DISTRIBUTIONGENERATOR“Distributed power means modular electric generation or storage located near the point of use” according to Ministry of Power. It includes biomass generators, combustion turbines, micro turbines, engines generator sets and storage and control technologies.Distributed power generation systems range typically from less than a kilowatt (kW) to ten megawatts (MW) in size.20 December 2012 Jitendra Singh Bhadoriya 3

  7. 7. METHODOLOGY PSO Particle Swarm Optimization is an Optimization Technique to evaluate the optimal solution . Evolutionary computational technique based on the movement and intelligence of swarms looking for the most fertile feeding location It was developed in 1995 by James Kennedy and Russel Eberhart [Kennedy, J. and Eberhart, R. (1995). “Particle Swarm Optimization”, Proceedings of the 1995 IEEE International Conference on Neural Networks, pp. 1942-1948, IEEE Press.] (http://dsp.jpl.nasa.gov/members/payman/swarm/kennedy9 5-ijcnn.pdf20 December 2012 Jitendra Singh Bhadoriya 7 Jitendra Singh Bhadoriya
  8. 8. PARTICLE SWARM OPTIMIZATION• PSO is a robust stochastic optimization technique based on the movement and intelligence of swarms.• PSO applies the concept of social interaction to problem solving.• It was developed in 1995 by James Kennedy (social- psychologist) and Russell Eberhart (electrical engineer).• It uses a number of agents (particles) that constitute a swarm moving around in the search space looking for the best solution.• Each particle is treated as a point in a N-dimensional space which adjusts its “flying” according to its own flying experience as well as the flying experience of other particles.20 December 2012 Jitendra Singh Bhadoriya 8 Jitendra Singh Bhadoriya
  9. 9. PSO• Each particle keeps track of its coordinates in the solution space which are associated with the best solution (fitness) that has achieved so far by that particle. This value is called personal best , pbest.• Another best value that is tracked by the PSO is the best value obtained so far by any particle in the neighborhood of that particle. This value is called gbest.• The basic concept of PSO lies in accelerating each particle toward its pbest and the gbest locations, with a random weighted accelaration at each time step as shown in Fig.120 December 2012 Jitendra Singh Bhadoriya 9 Jitendra Singh Bhadoriya
  10. 10. PSO PARAMETER sk+1 vk vk+1 vgbest vpbest sk Fig.1 Concept of modification of a searching point by PSO sk : current searching point. sk+1: modified searching point. vk: current velocity. vk+1: modified velocity. vpbest : velocity based on pbest. vgbest : velocity based on gbest20 December 2012 Jitendra Singh Bhadoriya 10 Jitendra Singh Bhadoriya
  11. 11. PSO Equation The modification of the particle’s position can be mathematically modeled according the following equation : Vik+1 = wVik +c1 rand1(…) x (pbesti-sik) + c2 rand2(…) x (gbest-sik) ….. (1) where, vik : velocity of agent i at iteration k, w: weighting function, cj : weighting factor, rand : uniformly distributed random number between 0 and 1, sik : current position of agent i at iteration k, pbesti : pbest of agent i, gbest: gbest of the group.20 December 2012 Jitendra Singh Bhadoriya 11 Jitendra Singh Bhadoriya
  12. 12. weighting function w• The following weighting function is usually utilized in (1)• w = wMax-[(wMax-wMin) x iter]/maxIter (2)• where wMax= initial weight,• wMin = final weight,• maxIter = maximum iteration number,• iter = current iteration number.• sik+1 = sik + Vik+1 (3)20 December 2012 Jitendra Singh Bhadoriya 12 Jitendra Singh Bhadoriya

PSO ALGORITHMFor each particle Initialize particleENDDoFor each particle Calculate fitness value If the fitness value is better than the best personal fitness value in history, set current value as a new best personal fitness value End Choose the particle with the best fitness value of all the particles, and if that fitness value is better then current global best, set as a global best fitness value For each particle Calculate particle velocity according velocity change equation Update particle position according position change equation EndWhile maximum iterations or minimum error criteria is not attained 20 December 2012 Jitendra Singh Bhadoriya 13 Jitendra Singh Bhadoriya
