Abstract: The Economic Load Dispatch (ELD) and Economic Emission Dispatch (EED) have been applied for obtaining the ideal energy cost and ideal production of the producing units, individually. The destructive environmental impacts created by the discharge of particulate and vaporous contaminants like sulfur dioxide (SO2) and oxides of nitrogen (NOx) these can be minimal by the satisfactory measure of the heap between plants of a power framework. In any case, this prompts a prominent increment in the operational expense of the plants. This paper proposes a lambda based methodology for elucidation the Combined Economic and Emission Dispatch (CEED) issue utilizing Particle Swarm Optimization (PSO) and results is contrasted and the lambda-emphasis, Genetic Algorithm (GA) methods thinking about nonlinear attributes of the generator, for instance, Ramp Rate limits and the Prohibited Operating Zones. The reason for this Combined Economic and Emission Dispatch (CEED) is to minimalize both the operating fuel cost as well as the emission level at the same time while fulfilling the load demand and the operational limitations. This multi-objective CEED problem is changed over into a single objective function using a modified price penalty factor approach. The dissimilarity constrictions due to the ramp rate limits are included by the combining with generation limits constraints and hence converted in to a single inequality constraint. For a precluded operating zone, the unit is made only to operate above or below the zone. An algorithm is developed in this undertaking to change the generation output of a unit so as to deny the unit task in the disallowed zones. In this work, incremental cost is taken as the encoded limitation PSO, which makes the issue autonomous of the quantity of generating components and the number of repetitions for conjunction reduces dramatically. The possibility of the planned lambda based method is proven for two dissimilar systems, and the result obtained from PSO method are compared with conventional and GA as far as the arrangement quality and computation efficiency.
