    PV Penetration for regulating voltage using reactive power
    (Altınbaş Üniversitesi, 2018) Noor, Ali Majid; Uçan, Osman Nuri; Bayat, Oğuz
    Power Networks have two major aspects one is the Safety of the network and the other is its economic, reactive power is the very important element to serve these two aspects. To avoid unwanted power quality and high transmission loss we should locate reactive power in reasonable way in power network. Currently, in order to keep the network voltage in acceptable range and the real power loss as minimum we use dispatch of reactive power in traditional way. Since the reactive power has inequality constrains and quality constrains, so we can consider it as a nonlinear problem. In my thesis, I will use MATPOWER 5.1 toolbox, PSO algorithm and matlab program and applied it to find the optimum reactive power dispatch allocation. The algorithm PSO is a comprehensive optimization algorithm that is equipped with the best searching ability. Advantage (major ones) of the PSO is that when the function of the object is more complex the efficiency of PSO does not effect. Because MATLAB toolbox is a global program and our work focus on power flow so we will use MATPOWER 5.1 as open source to solve the problem. Since MATPOWER Toolbox is a power source so when any one use it, it will help him and the code will be very easy. Also we will use OpenDSS program via MATLAB COM to see PV effect. Then we will discuss the effect of PV residential penetration via MATLAB simulation using 24 house examples with PV and without PV penetrations. Our goal is to minimize power loss in transmission lines and to allocate the reactive power in optimal placement. IEEE 24 bus system is used to calculate the performance.
