Economic power dispatch (EPD) is one of the main tools for optimal operation and planning of modern power systems. To solve effectively the EPD problem, most of the conventional calculus methods rely on the assumption that the fuel cost characteristic of a generating unit is a continuous and convex function, resulting in inaccurate dispatch. This paper presents the design and application of eff...

This paper presents a review of the achievements of the optimal power dynamic dispatch problem since its inception to the present. There exist two formulations for this problem in the literature. The first formulation is the optimal control dynamic dispatch (OCDD), where the power system generation has been modelled as a control system and optimization is done in the optimal control setting wit...

Reactive power dispatch, which may have many local optima, is an important and challenging task in the operation and control of electric power system. This paper presents a Selfadapti ve Differential Evolution hybrid Particle Swarm (SaDEPS) optimization algorithm for optimal reactive power dispatch problem. In this method, each particle is updated by a randomly selected strategy from a candidat...

With the advent of gravitational wave astronomy and first pictures “shadow” central black hole our milky way, theoretical analyses holes (and compact objects mimicking them sufficiently closely) have become more important than ever. The near future promises detailed information about observable candidates. This could lead to advances on constraints or evidence for modifications general relativi...

This paper reports an ethnography of ambulance dispatch work in a large UK metropolitan region. The interplay between control centre ecology, usage of a computerised dispatch system, and cooperative work of control personnel is analysed. The methods by which a 'working division of labour' is sustained to effectively manage dispatch in the face of high workload and manifold contingency are expli...

This article focuses the application of Levy flight based PSO algorithm for the solution of micro grid power dispatch problems. The proposed algorithm is tested on micro grid dispatch problem consisting of wind, diesel and fuel cell plants. The effectiveness of the algorithm has been verified on a test system having distributed generation compared with the other existing techniques, considering...

The increasing growth of non-dispatchable renewable energy sources (RES) such as solar and wind and the upcoming plug-in electric vehicles (PEVs) makes the secure power dispatch a challenging optimisation. In this paper, a coordinated power dispatch strategy in microgrids with a battery management system is proposed. The power dispatch strategy dynamically fits the power production to the power...

The economic dispatch of wind power units is quite different from that in conventional thermal units; since the adopted model should take into consideration the intermittency nature of wind speed as well. Therefore, this paper uses a model that takes into account the aforementioned consideration in addition to whether the utility owns wind turbines or not. The economic dispatch is solved by usi...
