Preface
Strategic research agendas worldwide on electricity transmission and distribution
networksemphasizethatby2030,electricitynetworkswillcontinuetofunctionina
manner that optimizes cost and environmental performance without giving up
traditionally high security and quality of supply, while hosting very large and
further increasing penetration of renewable and distributed (dispersed) generation.
Stimulation of local production of renewable energy requires the emergence of
more intelligent transmission and distribution networks with a view to accommo-
date variable generation from multiple sources and a growing demand for renew-
able energy. Electricity wholesale competition and the deregulation of retail
electricity markets with the energy value chain becoming bidirectional are models
that have been internationally adopted in an effort to achieve the maximum eco-
nomic benefits and energy savings. Finally, energy efficiency is by far the greatest
opportunity for the power industry in the current energy market, with all the
electricity market participants trying to approach it in the most effective way in
order to achieve significant competitive advantages.
Taking into consideration the important changes and the reformation of the
powerindustrythatarecarriedouttoday,aspreviouslydescribed,thecurrentbook
provides intelligent and innovative solutions that can be applied on electricity
transmission and distribution networks to support these changes. Throughout the

mission and distribution networks and finally on issues related to the economics
of the power industry.

A Methodology for Web-Based Power
Systems Simulation and Analysis
Using PHP Programming
Simon Agamah and Lambros Ekonomou
Abstract A methodology for carrying out web-based power systems simulations
using PHP programming for the simulation engine is described in this chapter.
Power system simulation is essential for planning and studying how an electrical
network system will operate over time without physically assembling it. The
methodology is implemented in a modular object-oriented PHP application that
computesthepowerflowsolutionofelectricalnetworksusingtheNewton-Raphson
method. A key difference between this solution and existing web-based power
systems simulation applications is in the architecture; other solutions use a 3-tier
structure:webbrowser,webserverscriptsandsimulationenginewhilethishasthe
simulation engine running in the web server scripts thereby creating a slimmer
2-tier structure. This 2-tier structure and the choice of PHP has considerable
implications in terms ofserver resources required toexecute thesolution,whichis
increasinglyimportantinthiseraofcloudcomputing,Software-as-a-Service(SaaS)
andsmartelectricitynetworks.Themethodologycoversthemorerecentfeaturesof
PHP that make it possible to carry out such analysis which were not present in
previousversionsofthelanguage.Italsocovershowadditionalclassesrequiredto
