Abstract<br />

This paper deals with the development of a horizontal variable speed wind turbine model,<br />

and the design and analysis of an optimal controller. The optimisation criteria will have to define<br />

an acceptable compromise between the limitations of the power level in the above rated wind<br />

speeds and the maintenance of the aerodynamic properties of the rotor at high solicitations<br />

exerted by the wind. The main control objective is to provide an amount of energy that will not<br />

exceed the nominal parameters of the generator and thus avoid overheating.<br />

Rezumat<br />

Această lucrare descrie un Microgrid controlat de sisteme multiagent. ReŃeaua electrică<br />

existentă are multe probleme.<br />

Printre acestea sunt: subcapacitate, lipsa de calitate a energiei electrice şi poluarea<br />

mediului. Modernizarea infrastructurii şi înlocuirea echipamentelor şi dispozitivelor vechi este o<br />

modalitate de a ajunge relativ rapid la standardele impuse de Smart Grid. O altă soluŃie de a<br />

furniza energie de înaltă calitate şi non-poluantă este conceptul de Microgrid. Aceasta retea se<br />

bazează pe energie regenerabilă din unităŃi numite generare distribuită (DG). Din<br />

păcate, acest tip de de sursa de energie nu poate asigura un flux constant de energie.<br />

Integrarea Microgrids în reŃelele electrice este urmatorul pas spre realizarea Smart Grid. Un design<br />

high-level de microgrid este prezentat în acest articol. O abordare distribuita a fost adoptată<br />

în modelarea Microgrid.<br />

Cuvinte-cheie: Microgrid, Sisteme multi-agent, DG, Smart Grid<br />

Abstract<br />

This paper describes a Microgrid controlled by Multiagent Systems. Existing electrical grid<br />

has many problems.<br />

Among them are: undercapacity, lack of power quality and pollution of the environment.<br />

Upgrading the infrastructure and replacing old equipments and devices is one way of reaching<br />

relatively fast the standards comprised by Smart Grid. Another solution of providing high quality<br />

and non-polluting energy is the concept of Microgrid. These grids rely on renewable energy from<br />

units called Distributed Generation (DG). Unfortunately this type of power sources cannot provide<br />

a constant energy flow.<br />

Integration of Microgrids in electrical networks is the next step towards achieving Smart<br />

Grid. A high level design of microgrid is presented in this article. A distributed approach was<br />

adopted in modeling the Microgrid.<br />

Rezumat<br />

Chiar dacă are un caracter regional şi intermitent, energia regenerabilă este curată şi<br />

practice inepuizabilă, fiindu-i asigurată de la sine acceptabilitatea cerută pentru dezvoltarea<br />

durabilă. Cu precădere în regiuni izolate sau gospodării agricole, unde biomasa tradiŃională şi<br />

energia hidro joacă un rol important, sursele regenerabile contribuie la creşterea disponibilităŃii<br />
