MATLAB Implementation of Solving Combined Economic and Emission Dispatch by Metaheuristic Algorithm
Understanding the Combined Economic and Emission Dispatch Problem
The CEED problem involves two main objectives:
Economic Dispatch: This focuses on allocating power generation among different units to minimize the total fuel cost while meeting the load demand.
Emission Dispatch: This aims to reduce the environmental impact by minimizing the emissions produced by the power generation units.
The goal of CEED is to combine these two objectives, ensuring that both fuel and emission costs are optimized simultaneously.
Constraints and Objective Function
To effectively tackle the CEED problem, several constraints need to be addressed:
Load Demand: The total power generated must meet the load demand plus any losses in the system.
Generation Limits: Each power generation unit has minimum and maximum output limits that must be adhered to.
The objective function combines these aspects by formulating a single equation that represents both fuel and emission costs. This function is then minimized using optimization algorithms to find the optimal power generation schedule.
Exploring Metaheuristic Algorithms
The video presents several metaheuristic algorithms implemented in MATLAB to solve the CEED problem. Here’s a summary of each algorithm covered:
Genetic Algorithm (GA): This evolutionary algorithm mimics natural selection to find optimal solutions. The MATLAB code for GA includes data setup, objective function formulation, and algorithm execution with parameters such as population size and generation count.
Particle Swarm Optimization (PSO): PSO simulates the social behavior of swarms to explore and exploit the solution space. The implementation involves setting up particle data, objective functions, and running the optimization with specified iterations.
Black Widow Optimization (BWO): This algorithm is inspired by the predatory behavior of black widow spiders. The MATLAB code demonstrates how BWO is used to minimize the combined cost function.
Algorithm Implementations and Results
The blog details the MATLAB implementations and results of various algorithms:
Genetic Algorithm: The GA implementation results in a fitness value representing the optimized fuel and emission costs. The final output includes detailed power generation for different units.
Particle Swarm Optimization: The PSO results show how the algorithm converges to a solution, with variations in fitness values over iterations.
Black Widow Optimization: BWO is demonstrated with its code and results, highlighting its effectiveness in minimizing the CEED problem.
Additional Algorithms: Other algorithms such as Swarm Optimization, Multiverse Optimization, Flower Pollination, Dragonfly Algorithm, and Bat Algorithm are also discussed. Each algorithm is executed in MATLAB, and their results are compared based on fitness values and power generation outputs.
