The communication between various intelligent network devices for the ADMS interfaces, it is necessary to deploy an appropriate communication network to meet the requirements of all intelligent network components.A very common problem encountered in smart grid design and deployment lies in the definition of the communication network that will serve the project. Many ways of developing communication network projects have been tested in Brazil, all in urban areas where the cellular network is abundant and the endpoints are close to each other.In this paper, we list all the steps that led us to decide on the adoption of a LoRaWAN communication network and how this network is being implemented in the CPFL / UFSM / ANEEL project in southern Brazil in a rural area and testing with experimental LORAWAN network in UFSM Campus.

This paper proposes a dynamic optimization mathematical approach to obtain the optimum mix of distributed generation plants with renewable energy resources (RER) necessary to provide reliability to critical electrical systems. This model takes as inputs the energy potential ofwater, wind and solar resources available and injectable in each area, investment and operation and maintenance (O&M) cost ofthese plants and related infrastructure; as well as parameters of existing electrical grid and conventional generation plants. The proposed model is performed for the 8760 hours of a typical year within which it is considered out-of-service states for existing transmission lines and power plants. A robust approach is contemplated though a cost sensibility analysis. The results of the application performed in a real case in Puno, Peru evidence an improvement of approximately 81% and 68% in reliability indexes SAIDI and SAIFI, respectively.

This paper specializes on the real-time simulation of the Prony filter for capturing low frequency dynamics in power systems. The development is accomplished integrating two platforms: OPAL-RT and Matlab & Simulink. Where a computational efficient Prony calculation is implemented in order to yield damping and frequency estimates in short-time. The analysis is performed through a sliding analisys window, which it is used to guarantee instantaneous estimates. The low frequency oscillations’ identification process is applied on two systems. Experimental results confirm the propositions performance, precision, and reliability.

The operating point (OP) of energy storage systems (ESS) may change drastically and with a certain frequency, depending on their dispatch. In order to use this technology to its full extent, such condition should not represent a limiting constraint in terms of performance and stability. However, linear controllers as the proportional-integral-derivative (PID) generally require the linearization of the system around a point to perform their tuning and do not necessarily guarantee correct operation over the wide range required by ESSs. In order to address this issue, this paper presents a study to select a consistent OP when tuning the PIDs for the active power control loop in an ESS. Two scenarios of simulated OPs were obtained from an optimal power flow (OPF) (critical setpoint shifts, and centroids of clusters for representative cases), with a third one to evaluate saturation. A genetic algorithm (GA) was used at each point to minimize reference tracking error and to ensure operating constraints. The simulation results were confirmed through a mathematical analysis which indicates that since the system’s behavior depends heavily on the OP, tunings based on saturation points are the most consistent choice.

The Colombian power system will have an important challenge in the upcoming years because of the large amount of unconventional renewable energies that are going to be connected to it. This power system typically has been hydro based with no presence of large-scale wind or photovoltaic generation. Around 1249 MW of wind and 1086 MW of photovoltaic large scale generation are expected which represents 10% of the peak demand. For this reason, the Colombian power system operator must evaluate the impact of integrating these technologies into the grid. In order to achieve this goal, the behavior of these unconventional renewable generators was simulated using the WECC (Western Electricity Coordinating Council) control model for Type 4 Wind Generators which was implemented in the PowerFactory software. This paper shows the results of several tests carried out to validate the referred model and the analysis performed with it to assess the impact of these sources in the Colombian power system’s frequency and voltage. Using these results the technical requirements were defined to maintain the security and reliability conditions of the power system.

The Transmission Expansion Planning (TEP) problem determines the optimal investments for certain candidates’ transmission lines in an electric power system. The TEP problem considers and implements the N-1 security criterion in all periods of planning and operation. This paper introduces a novel approach to reduce the computation time and memory used when modeling the TEP problem considering the security criterion N-1. Several popular commercial solvers are used to evaluate the computational efficiency of the proposed TEP approach.

The most common protective device in distribution systems is the expulsion fuse link. This work aims to assist the engineer in carrying out expulsion fuse links modeling using curve fitting. The proposed approach used the fuse time-current characteristic to obtain the polynomial function that represent the fuse link model. Preferred K and H fuses were used. The polynomial coefficients was obtained through the MATLAB software. The polynomial order that best represents the fuse link was decided using the cross-validation technique. The technique consists of iteratively partitioning the data set, separating test points and training points on each iteration.

The integration of photovoltaic generation (PV) is the subject of study of the distribution companies, universities and research centers around the world, since there is a goal to measure the impact of the presence of this type of generation in distribution systems. In this work, the technical losses (or ohmic losses) in medium voltage (MV) feeders were evaluated considering the insertion of the photovoltaic generation. In general, it is verified that the insertion of this generation is associated to the reduction of losses in the feeders, since there is an intuitive idea of reducing its load. However, through several simulations in the Simulight software [1], this work describes situations in which the ohmic losses increase, also evaluating other relevant factors that influence this issue.
