A Strategic Review on Economic Dispatch Distribution and Environmental Considerations

Power systems contain four generic parts, including production, transmission, dispatch distribution, and consumption. Generally, dispatch distribution between powerhouses modelled with the goal of minimisation in utilisation cost. However, Environmental concerns were given more attention to powerhouse emissions such as SO2, CO2 and NO cause to investigate modelling in recent researches. However consideration of the objectives of fuel cost and emission value in the dispatch distribution problems known as the eco-environmental dispatch distribution. Although Due to the paradox between the reduction of utility costs and external costs, different methods used.

Mean Variance

The economic dispatch (ED) is one of the important optimization problems in power system generation for fuel cost saving. This paper proposes a hybrid variant of mean-variance mapping optimization (MVMO-SH) for solving such problem considering the non-convex objective functions. The new proposed method is a hybrid variant of the original mean-variance mapping optimization algorithm (MVMO) with the embedded local search and multi-parent crossover to enhance its global search ability and improve solution quality for optimization problems. The proposed MVMO-SH is tested on different non-convex ED problem including valve point effects, multiple fuels and prohibited operating zones characteristics. The result comparisons from the proposed method with other methods in the literature have indicated that the proposed method is more robust and provides better solution quality than the others. Therefore, the proposed MVMO-SH is a promising method for solving the complex ED problems in power systems.

Environmental Considerations

The need for sustainable development underscores the role and importance of integrating environmental concerns in non-environmental policies because it is evident that environmental regulations only are insufficient to manage all environmental issues. Law enforcement on environmental protection in Vietnam clearly demonstrates this situation. Vietnam’s legal system of environmental protection is incompatible or overlapped with other sectoral laws and in fact many environmental matters have been implemented in accordance with sectoral laws while disregarding environmental considerations due to the lack of specific and explicit environmental provisions or requirements in sectoral laws and regulations. From that situation, the paper emphasizes the need to integrate environmental protection requirements into the sectoral laws of Vietnam and proposes some fundamental criteria and procedures to integrate environmental requirements into sectoral laws.
