The proposed method is applied to the abovementioned distribution network. According to a sensitivity analysis, the number of generations and the population size are chosen as, 300 and 20, respectively. The method has been implemented in MATLAB® incorporating some features of MATPOWER suite [19] and MAT – LAB® toolbox for GA [27] on a laptop […]

Load-Sharing Control Techniques for LV and MV Networks
The main objective of load-sharing is to distribute the active and reactive loads among the available DGs while maintaining voltage regulation and accommodating various types of loads [13]. In LV and MV networks, load-sharing becomes challenging due to the following factors. • Most DGs have some local loads, • Most DGs are non-dispatchable RESs, and […]
Impact of G2V on Grid
First-generation mass-market PHEVs, such as the Chevrolet Volt and Nissan Leaf [10, 11], connect to the grid for only battery charging, which is the most basic configuration. G2V includes conventional and fast battery charging systems, and the latter can stress a grid distribution network because its power is high, as a typical PHEV requires more […]
Analyzing the Benefits ofEV Participation on the MG Rebuilding
Figure 12.20 compares the MG frequency behavior during the reconnection of loads and non-controllable MS when considering both non-controlled charging and V2G service. At t = 5 s the MGCC enables the reconnection of the first load block causing a frequency deviation of 1.5 Hz, which is then corrected by the secondary control by increasing […]
DC-DC Converter
The power losses in a power electronic DC-DC converter can be divided into conduction and switching losses, where conduction losses consist of inductor conduction losses and MOSFET conduction losses [28] (Fig.14.7). • Inductor Conduction Losses Inductor conduction losses is as follows Pl = I2L x Rl {14.17) where Rl is the DC-Resistance of the inductor, […]
Illustrative Example and Results
To evaluate the performance of the MAS-based smart grid protection system for the impact of growing penetration of wind energy in the grid, a test system as shown in Fig. 16.2 is used for simulation under different wind power penetration level. In the following sections, we discuss about the function of individual autonomous agents which […]
Genetic Algorithm
A genetic algorithm (GA) is a procedure used to find approximate solutions to search problems through application of the principles of evolutionary biology. The evolutionary process of a GA is a highly simplified and stylized simulation of the biological version. It starts from a population of individuals randomly generated according to some probability distribution, usually […]
Series-Shunt Compensation
It is clear from the above analysis, that the advantage of both shunt and series compensation of an AC capacitor can be made use of. In shunt compensation, the capacitor is used to compensate the individual induction generators. In series compensation, the capacitor is used to compensate the line impedance. The overall result will be […]
