This paper presents a methodology and a computational tool developed for the assessment of the impacts caused by photovoltaic and wind generators, up to 100 kW, connected to the distribution networks, and aims at a real network application. The impact on the power distribution systems planning derive from the new network configuration caused by the installation of distributed generators and the demand growth. The curves associated with the distributed generators (DG) are modelled based on the average behavior of the inputs, such as irradiation and wind, and the technologies available. Their locations are defined by a DG probabilistic allocation algorithm based on attractiveness measures, as a function of economic variables. The network impacts consider prospective scenarios, and are determined by the diagnosis of network elements, by monitoring the loading of feeders and secondary networks, as well as the analysis of voltage profiles, losses, and protection effectiveness.

In the last decade the merchandise transportation has considered the insertion of Electric Vehicles (EVs) in their fleets, in order to reduce the negative environment impact generated by the Internal Combustion Engines (ICEs). Whereby, this paper addresses the solution of two combined problems: determining the Battery Swap Station Location (BSSL) and solving the Capacitated Vehicle Routing Problem (CVRP). The model presents a slight variation in its formulation reported in the specialized literature, which provides a better computational performance in the analyzed problems. The mathematical model implemented uses commercial software and the results were validated by different instances.

Smart Grid (SG) is becoming a reality in Brazil in many projects covering different areas such as smart metering, demand-side management and distributed generation. It is known that the communications infrastructure is an essential part for a successful implementation of SG architecture and the choice of a communication system is very particular due to several weaknesses in communication technologies. In order to reduce such weaknesses, it was developed a reference design for a hybrid communication module based on the universally adopted IP protocol with two communication channels: Radio Frequency (RF) and Power Line Communication (PLC). It was used IEEE P1901.2 and IEEE 802.15.4g protocols in order to provide interoperability, reliability and resilience for the network. This article aims to present the motivations, the communication module developed and the test results obtained in the validation stage in laboratory and on site. In addition, the project is exploiting regulations and restraining requirements.

The development and diversification of the Uruguayan power electric infrastructure, with the significant incorporation of renewable sources is leading to changes in the operation criteria. With all these efforts to make the power system more efficient and smarter, real-time analysis are becoming more required and necessary. This paper investigates a method of estimating the electromechanical modes from multiple synchrophasors. The application includes a method with the objective to provide the maximum observability information of the electromechanical modes of interest. The study specifically analyzes the performance of the method in the 10 machine 39 bus IEEE test system and in the Uruguayan power system.

Distributed generation systems (DGS) has become a promising alternative to meet the growing demand for electricity. The requirements for DGS systems justify the use of new control techniques that ensure stability and can handle the performance of the system. In this sense, passivity based control is a technique that takes advantage of the structure of the system by providing a better understanding of the control law. The main objective of this paper is to evaluate Power Shaping control to regulate active and reactive powers of an energy storage system in order to improve the performance of the electrical grid.

The number of photovoltaic distributed generators introduced into electricity distribution systems is increasing worldwide. Safety measures must be taken for the correct operation of these new distributed generators so as to prevent uncontrolled and undesired power injections into the grid and possible damages to equipment and personnel. This paper describes an anti-islanding detection method used for prevention against unintentional islanding of the distributed generator. The main focus is the study, implementation and analysis of the Sandia Frequency Shift method based on the IEEE 929-2000 standard.

Uruguay is changing its electricity generation matrix integrating a great amount of wind power. This implies that there will exist an energy surplus that can be exported to other countries or may be used in Uruguay if a new demand appears capable of absorbing this type or surplus. Examples of this type of demands may be intensive irrigation agriculture or the fleet of electric cars. This work shows an approximation to definition of a price signal that can be used by smart controllers distributed over the grid to manage such demands. Simulation of the proposed algorithm are carried out showing that the stability of the system is achievable.

This work presents a nonlinear control of a wind generator equipped with a Permanent Magnet Synchronous Generator (PMSG). Three SISO controllers are developed, a Passivity based controller for the PMSG and its converter, and two Lyapunov controllers for the DC link and for the grid side converter, respectively. A general Control Strategy is presented in order to pass severe faults as symmetrical grid voltage dips. The proposed controllers are tested under realistic wind conditions.

Because of the importance of power transformers to the electrical system, operating from transmission lines to distribution, understand their condition is critical. Analysis of dissolved gases in the insulating oil of transformers is an efficient and reliable way to perform a diagnosis. However, in some situation each method of dissolved gases interpretation can indicate one different type of fault. Thus, this paper present a multi-criteria decision making method that aggregates the information of four traditional methods, and indicates the condition of transformer. The results were promising, in way that was possible to obtain a consistent response through three different interpretations.
