The general flowchart of PSO is illustrated as follows:Fig. 2.3. Flowchart of PSO methodAdwantages of PSO:I'SO is a population-baaed ecolutionar) technique that has many advantagesover other optimization techniques. PSO is a derivati~e-frec algorithm unlike manyco~nentional techniques and is Iesc smsiti\,c lo the nature of the objective function.v~L.. convexity or continuity. I'hese swarm intelligence hased methods have fewparameters to adjust and escape local minima. I'he proposed method is easy toimplement and program with hasic mathematical and logical operation>. It can alsohandle objective functions with stochastic nature and does not require a good initialst)tution to start its iteration process.2.2.4. lmplementetion of PSO for ELD solutionThe main ohjectibe of ELD is to ohtain the amount of real power to begenerated by each cornmined generator, while achieving a minimum generation Cost
wlthln the constraints. The details of the implementat~on of PSO components aresummarized in the following subsections.2.2.4.1. Representation of an Individual StringFor an efficient evolutionary method, the representat~on of chromosomestrings of the problem parameter set is important [42]. Since the decision variables ofthe ELD problems are real power generations, the generation power output of eachunit IS represented as a gene, and many genes compnse an individual in the swarm.Each individual within the population represents a candidate solution for an ELDproblem. For example, if there are d units that must be operated to provide power toloads, then the ilh individual Pg, can be defined [42] as follows:Pg, =[P,,,P ,. ....... P,,], i=1,2 ..... n (2.10)where n means population size, d is the number of generator, Pbd is thegeneration power output of d'h unit at individual i. The dimension of a population is(n x d). These genes in each individual are represented as real values. The matrixrepresentation of a population is as follows:Individual p, I p12number2.2.4.2. Evaluation FunctionThe evaluation function for evaluating the minimum generation cost of eachindividual in the population is adopted [42] as follows:dMinimizeF, = CF,(P,) (2.11)I-)
