This paper presents a brief behavior description of LCL filters through the analysis of its frequency response and the convenience of its use instead L filters. Moreover, the equations that allow its design and implementation are also described. Regarding the Proportional Resonant (PR) controllers, their behavior, discretization techniques and digital implementation are also studies. The developed systems are evaluated by mathematical model simulation and experimental prototype test. It is concluded that, for inverters operating as a current source, the PR controllers are suitable to follow a sinusoidal reference signal. On the other hand, LCL-type filter largely eliminates the harmonic content of the output current, making it compatible for Grid-Connected PV micro-inverters.

This paper presents a new method for the optimal sizing of photovoltaic systems in distribution networks, in order to reduce energy losses and improve the voltage profile. The DIgSILENT PowerFactory software, specifically the DIgSILENT programming language (DPL) was used for implementation of this method. Photovoltaic systems are modeled as constant power, and the optimization method has the ability to determine the sizing for distributed generation units. The effectiveness of the method was tested in the 60-bus insolated electrical system of Iquitos with excellent results, which are discussed and commented.

The identification of the values with good accuracy of physical parameters of transmission systems is very important because using very different values from the real ones seriously distorts the evaluation of the planning, design, operation, maintenance and commercialization of the transmission systems. The present work describes the identification of physical parameters of a real transmission system using a mathematical model with variable values of the physical parameters. The identification is done by comparing the real operation of the system with the simulated operation of the model, varying iteratively the physical parameters values of the mathematical model. To this purpose two different techniques were applied, a classical and a modern meta-heuristic technique to 47 high voltage transmission lines of the Peruvian electrical system. The real operation is obtained from the database of the measurements of the operating variables of the transmission system. The correct values of the physical parameters will be those that correspond to the simulated operation identified. This paper is organized as follows: Section II describes the philosophy of the parameter estimation problem, here is included the symbology, the model of the transmission system, the formulation of the problem and its solution. In section III, the results of the identified parameters are presented and discussed. Finally, in section IV the conclusions are presented.

The objective of this work is to evaluate the insertion of Electric Vehicles (EVs) on a distribution system. Motivated by the shortage of deterministic data regarding to the power demand required by EV charging in Brazil, a probabilistic methodology is proposed to estimate this impact. For that, energy consumption and urban mobility patterns from a pilot region are used to compose the distribution transformer load curve. Both energy consumption for EVs and typical consumer demand take into account the probabilistic nature of load. Therefore, the Monte Carlo method applies for both situations, Base Scenario and EV Scenario. From the union of both scenarios, the load curve of the distribution transformer is evaluated regarding to the influence of different EV penetration levels. The results can be used by energy distributors as a support tool for the decision to prioritize the investments in distribution transformers.

The growing interplay between natural gas and electricity systems can be traced back to the increasing installation of natural gas fired power plants. Indeed, these generation units are significant demands for the gas system while they are important producers in the power system. This interrelationship has driven the need to model in detail these energy carrier systems in combined manner to properly capture these interactions and to optimize the management of energy resources from a centralized planning perspective. Presently, most electricity and natural gas systems are operated and optimized separately. Natural gas prices and available volumes for the electric power generation are used as fixed parameters for targeting coordination between both energy sectors. Nevertheless, this approach to coordination leads to substantial deadweight losses for both energy systems. With the aim of quantifying the economic impact of integrating the operational planning of both energy carriers, this paper assesses and compares the medium term scheduling of power and natural gas systems when the systems are considered in a coupled and decoupled manner. In order to obtain realistic results, the Argentinean energy system is used as exemplary case study including their associated power and gas networks.

Low frequency oscillation modes of a multi-machine power system, as affected by the implementation of a VSC-HVDC link between system areas, are investigated in this paper. For this purpose, a set of test cases for the operation of the DC link alone and in parallel with AC lines in a corridor are considered. Small-signal stability analysis and time domain simulations are performed to evaluate the impact of the HVDC link on system stability and performance. Eigenvalue analysis and results of simulation studies show the relative enhancement of system dynamics with the inclusion of the HVDC link.

This paper studies the changes which has been occurring by the connection of distributed energy resources (DER) in the electrical distribution system. The big number of houses acquiring the photovoltaic generation system connected on-grid, increases the challenge of the distribution system company in maintain the service entrance voltage within service range. One problem of the on-grid system is that the network presents a big voltage fluctuation by the unpredictable resultant load profile in each residence that depends the instantaneous house power generation and consumption. While the big injection increases, the low injection of energy decreases the nominal house voltage, and without some kind of control, this voltage fluctuation is able to impact not only the own voltage profile, but also the neighbors’ voltage profile. For this reason, this paper proposes a smart local voltage control that uses an energy storage system (ESS) and Volt-VAr control in each house, triggering them when it is more conventional, maintain the nominal house voltage within the service range. Different from others studies, this local control is developed looking for small changes that when added, can impact in a positive way the entire system, improving the voltage profile and not overloading the voltage regulators and capacitor banks along the network. All control was developed, tested and analyzed on Matlab/Simulink, where was used a modified version of the IEEE 34-bus test feeder as case study.

The optimal reconfiguration of radial Electrical Distribution Systems (EDSs) is a classical optimization problem that deals with the operation of the system and is of great interest to the electricity sector. Although there is a large number of approaches in the specialized literature to solve this problem, the solution of the reconfiguration problem for large-scale EDSs is still difficult. This paper proposes a method to solve the reconfiguration problem of EDSs that is based on the specialized metaheuristic Biased Random-Key Genetic Algorithm, which showed excellent performance on the solution of complex problems in operational research. Tests carried out using a wellknown EDS demonstrate the efficiency of the proposed method.

The article is devoted to the issues of ensuring a steady operation of an autonomous power supply system with a wind-diesel power plant (WDPP). The proposed approach is based on maintaining active and reactive power balances in the system, and includes calculating and controlling the power balance coefficient. The authors used the simulation model of the autonomous power supply system with the WDPP, carried out studies to find out dependences of the balance factors on the parameters of the system and obtained its operating mode. An algorithm for ensuring the WDPP normal operation modes has been developed. The algorithm is universal and can be used to develop an autonomous power supply system with any type of distributed power generation sources.

The validation of a methodology for power system protection performance analysis using the Real Time Digital Simulator (RTDSTM) and an actual numerical relay is presented in this paper. The validation was accomplished through a software named DAPPE (Disturbance Analysis and Protection Performance Evaluation), developed by the authors to give support to São Francisco’s Hydroelectric Utility Company (CHESF) crew during the preparation of short-circuit reports, which must be sent to regulatory organizations whenever a transmission line (TL) fault occurs. Functions such as distance and overcurrent protection routines, phasor estimation, circuit breaker opening detection, fault detection, classification and location techniques, among others are embedded in DAPPE, which has an open and modular architecture where new protection functions can be easily added. The obtained results show that methodology embedded in DAPPE is reliable and quite useful for protection performance evaluations.
