Optimal Distributed Generation (DG) Allocation in Distribution Networks using an Improved Ant Colony Optimization (ACO) Algorithm

Abstract: The development of distributed generation (DGs) units in recent years have created challenges in the operation of power grids, especially distribution networks. One of these issues is the optimal allocation (location and capacity) of these units in distribution networks. In this thesis, a method based on the improved ant colony optimization algorithm is presented to solve the problem ...

An Ant Colony Optimization Algorithm for Network Vulnerability Analysis

Intruders often combine exploits against multiple vulnerabilities in order to break into the system. Each attack scenario is a sequence of exploits launched by an intruder that leads to an undesirable state such as access to a database, service disruption, etc. The collection of possible attack scenarios in a computer network can be represented by a directed graph, called network attack gra...

An Improved Ant Colony Optimization Algorithm for Solving TSP

The basic ant colony optimization (ACO) algorithm takes on a longer computing time in the search process and is prone to fall into local optimal solutions, an improved ACO (CEULACO) algorithm is proposed in this paper. In the CEULAC algorithm, the direction guidance and real variable function are used to initialize pheromone concentration according to the path information of undirected graph. T...

Improved Clonal Selection Algorithm Combined with Ant Colony Optimization

Both the clonal selection algorithm (CSA) and the ant colony optimization (ACO) are inspired by natural phenomena and are effective tools for solving complex problems. CSA can exploit and explore the solution space parallely and effectively. However, it can not use enough environment feedback information and thus has to do a large redundancy repeat during search. On the other hand, ACO is based...
