Minimization of fuel cost is the primary type of optimal power flow issues. Real power generators of various generators are the control variables in ELD issue. Optimal real power scheduling will ensure economic advantages to the power framework administrators and reduce the release of polluting gasses. Previously, various conventional optimization calculations are misused for taking care of the optimal power flow issues. A major objective of thermal power generation is to reduce fuel consumption by allocating optimum power generation to every unit i.e. economic dispatch and to take care of emissions at intervals the environmental license limits i.e. emission dispatch subject to equality and difference constraints. Owing to conflicting nature of emission and economy objectives downside becomes multi-objective in nature. Power grid stability has been recognized as a very important downside for its secure operation. Owing to increase in power demand, trendy power grid networks area unit being operated below extremely stressed conditions. During this thesis we are going to make out the simplest worth when convergence of minimum iteration. After that, we are going to optimize the economic dispatch and emission dispatch victimization game theory algorithmic rule.

INTRODUCTION Today electrical power plays an exceedingly important role in all walks of life of an individual as well as the community. The development of various sectors such as transportation, industrial, agricultural, entertainment, information and communication sectors etc depend on electrical energy. In fact, the modem economy is totally dependent on the electricity as a basic input. This is turn has led to the increase in the number of power generating stations and their capacities and the consequent increase in power transmission lines which connect the generating stations to the load centres. Interconnections between generating systems are also equally important for reliable and supply quantity of power system which also provide flexibility in system operation. Among different issues in power system operation, economic load dispatch (ELD) and optimal power flow (OPF) problem constitute a major part. 2. ECONOMIC LOAD DISPATCH Scarcity of energy resources, increasing power generation costs and ever growing demand for energy necessitate optimal economic dispatch in modern power systems. The main objective of economic dispatch is to reduce the total power generation cost while satisfying various equality and inequality constraints. Traditionally, in economic dispatch problems, the cost function for generating units has been approximated as a quadratic function. A wide variety of optimization techniques have been applied to solving Economic Load Dispatch (ELD). Some of these techniques are based on classical optimization methods, such as linear programming or quadratic programming to solve ELD problems. By economic load scheduling we mean to determine the generations of different plants such that total operating cost is minimum and at the same time the total demand and the
