Optimization of the Economic Dispatch problem by considering the emission dispatch with using the AMPSO

Abstract

In this paper, the problem of economic dispatch (ED), which is a problem with a nonlinear cost function, is solved using the proposed method. The ED problem, in addition to having a nonlinear function, also has a series of equal and unequal constraints that must be respected. Another important consideration when generating energy by power plants is, in addition to the cost, the issue of polluting the environment. In other words, in order to provide the power needed by consumers, in this issue two goals, reducing production costs and reducing the amount of emission, can be raised. This article covers all of the above issues. In this paper, an ultra-innovative algorithm is proposed to solve the problem. The proposed algorithm is based on the Particle Swarm Optimization algorithm. The proposed method is implemented on the systems under study with different conditions and the results obtained by AMPSO method are evaluated by other methods such as SA, NSGA-II and NSGA-III. The results show that the AMPSO produces optimal or nearly optimal solutions for the study systems.

Multi-Power Joint Peak-Shaving Optimization for Power System Considering Coordinated Dispatching of Nuclear Power and Wind Power

“…The output constraints, climbing speed constraints and minimum start-stop time constraints of coal-fired units are presented by (13). The output constraint, climbing rate constraint and minimum start-stop time constraint of combined cycle units is given by (14). Limits on wind power output are presented by (15).…”

“…Due to the negative peak shaving characteristics of wind power, it will force the conventional units to start and stop frequently, which is not in line with the principle of economic grid dispatching and leads to severe wind abandonment [14][15][16]. Therefore, for the coastal power systems with wind and nuclear power, it is of great significance to study the participation of nuclear power in peak shaving and coordinated dispatching with wind power for the economic operation of the power grid and the promotion of wind power consumption.…”
