Short-term non-convex economic hydrothermal scheduling using dynamically controlled particle swarm optimization
Paper presented to the 3rd Southern African Solar Energy Conference, South Africa, 11-13 May, 2015.The aim of this paper is to present short-term hydrothermal scheduling (STHS) of power system. This problem is solved in such a way that utilizes available hydro reserves optimally and thus minimizes the fuel cost of thermal plants. A PSO based method is developed which can efficiently deals with hydro constraints like reservoir storage volume limits, water discharge rate limits, water dynamic balance, initial and final reservoir storage volume limits, etc. for a given time horizon. The operators of the PSO are dynamically controlled. Moreover, the cognitive and social behaviors of the swarm are modified for better exploration and exploitation of the search space. The effectiveness of the proposed method has been investigated on a standard test generating system considering several operational constraints pertaining to hydrothermal systems.dc201
Shortest Route at Dynamic Location with Node Combination-Dijkstra Algorithm
Abstract— Online transportation has become a basic
requirement of the general public in support of all activities to go
to work, school or vacation to the sights. Public transportation
services compete to provide the best service so that consumers
feel comfortable using the services offered, so that all activities
are noticed, one of them is the search for the shortest route in
picking the buyer or delivering to the destination. Node
Combination method can minimize memory usage and this
methode is more optimal when compared to A* and Ant Colony
in the shortest route search like Dijkstra algorithm, but can’t
store the history node that has been passed. Therefore, using
node combination algorithm is very good in searching the
shortest distance is not the shortest route. This paper is
structured to modify the node combination algorithm to solve the
problem of finding the shortest route at the dynamic location
obtained from the transport fleet by displaying the nodes that
have the shortest distance and will be implemented in the
geographic information system in the form of map to facilitate
the use of the system.
