Combined heat and power (CHP) is the fuel unbiased method of production of heat energy and electrical power. Increased efficiency to the tune of 80% and above and reduced emission are two key attributes of this method as the production is obtained in a single process. This dissertation considered prohibited operating zones (POZ) and valve point effect (VPE) of generators in the study of Static Optimal load flow of CHP with the objective to reduce production cost while voltage level of buses are maintained within specified limit in order to satisfy the electrical power and heat demands. Optimization of load flow through such a power system is done using bio-inspired Social Spider algorithm. The distance of spider from food is defined as objective function. Two test systems having six generators in each have been used in IEEE 30 bus framework to demonstrate the efficacy of this algorithm. Results show that this method is competent enough to solve problem of multi objective optimization.
