tailieunhanh - Novel optimal coordinated voltage control for distribution networks using differential evolution technique

This paper investigates a Distributed Generators (DG) connected to distribution networks offering multiple benefits for grids and environments in the case of renewable sources used. Nevertheless, this task requires an appropriate planning and control strategy, if not several drawbacks can issue, including voltage rise problems and increased power losses. To overcome such disadvantages, this paper proposes a coordinated voltage control CVC method for distribution networks with multiple distributed generators. | Journal of Computer Science and Cybernetics, , (2018), 3–16 DOI NOVEL OPTIMAL COORDINATED VOLTAGE CONTROL FOR DISTRIBUTION NETWORKS USING DIFFERENTIAL EVOLUTION TECHNIQUE HO PHAM HUY ANH1 , CAO VAN KIEN Faculty of Electrical-Electronics Engineering (FEEE), Ho Chi Minh City University of Technology, VNU-HCM, Viet Nam; 1 hphanh@ Abstract. This paper investigates a Distributed Generators (DG) connected to distribution networks offering multiple benefits for grids and environments in the case of renewable sources used. Nevertheless, this task requires an appropriate planning and control strategy, if not several drawbacks can issue, including voltage rise problems and increased power losses. To overcome such disadvantages, this paper proposes a coordinated voltage control CVC method for distribution networks with multiple distributed generators. This new method is based on a differential evolution DE approach to obtain the optimal setting points for each control component. Furthermore this proposed method considers both of time-varying load demand and production, leading to not only an improvement in the voltage profile but also to optimally minimizing the active power loss. Keywords. Optimal Coordinated Voltage Control (CVC), Distributed Generators (DG), Differential Evolution DE algorithm, active power loss minimization, On Load Tap Changing OLTC. 1. INTRODUCTION Nowadays, distributed generation (DG) has become an important alternative to compensate for the increase of energy demand. DGs, such as solar and wind, are generally more environmentally friendly. Furthermore, by installing DGs close to consumer centres, the need to build new traditional generation plants (hydro-electric, thermal, nuclear) and new transmission lines can be reduced. Renewable distributed generators (DG) connected to grids offer multiple advantages, including active power loss reduction and voltage profile improvement, along with .
