The voltage regulation problem is very complex and important in electric power systems. Such problem is related to keep the voltages within pre-determined levels according to the current legislation. The application of smart grids' concepts helps in this problem by giving more background to take decisions and enabling the possibility of considering a wider picture of the power system to take control actions. This paper proposes a multobjective voltage control in smart distribution systems using Artificial Immune Systems. The proposed methodology considers the active power losses, nonconformity voltage levels fines and switching costs as variables. The IEEE 34 node test feeder and a real feeder are used as examples to assess the methodology robustness.

To deal with frequent planned and unplanned grid power outages, local energy systems are becoming popular idea. These systems are equipped with storage devices and different distributed generations (DGs) such as diesel generators. Efficient and reliable operation of local power systems is complex since power outages are stochastic events, and also local energy suppliers have different operation costs, constraints, and efficiency characteristics. A power management system (PMS), consisting of two control layers is developed in this paper to address aforementioned complex operation. To validate the proposed method, energy system of a base transceiver station (BTS) in India is simulated. It composed of batteries, diesel generator, real BTS load data, and a utility connection. In addition, the real historical outage data from India has been utilized to simulate outage events.

The main purpose of this paper is to introduce the development of a simulation model in order to evaluate the impact of massive recharge of Electrical Vehicles (EVs) on distribution networks in Bogotá, Colombia, taking into account specific EVs user behavior scenarios. EVs recharge is characterized and represented by software models based on EVs test measures and existing distribution networks topologies. Impact evaluation includes observation of node voltages, regulation and transformers loadability. Results are obtained from the simulations reproducing the consequences of the inclusion of EVs charging points inside the systems. Finally, according to the information obtained, Demand Side Management (DSM) strategies regarding the inclusion of EVs in energy distribution systems are proposed.

Supercapacitors-based storage systems are expected to play a key role in microgrids in view of their capability to compensate high-power imbalances. We define an agent for the control of supercapacitor arrays within the context of the novel control framework Commelec, proposed by the Authors as a composable method for real-time control of active distribution networks with explicit power setpoints. An important function of such an agent is to advertise the real-time power capabilities and operational preferences of the supercapacitor array based on local information. Given the small energy capacity of such a device, its internal state can largely vary from one setpoint implementation to the next one. For this reason, the use of an accurate model is crucial in the agent definition. We show that it is possible to infer the real-time power capabilities of the device by using simple measurements on the supercapacitor array suitably coupled with an accurate representation of the cells composing the array. Results show that the agent is able to speak for the resource, thus allowing its use from an external controller.

In this paper, we propose a hybrid wireless mesh network infrastructure which connects the smart meters of each consumer with the data aggregation points (DAP). We suppose a set of smart meters that need to send information, and receive information from a central office on electrical enterprises, employing the meter data management system (MDMS), and so forming the advanced metering infrastructure (AMI) stage of smart grids. We consider a multi-hop system, where information is routed through several nodes which act as DAP. Wireless mesh networks are known to extend coverage and increase deployment efficiency, so they could be an alternative for the connection between Home Area Network (HAN) and the Neighborhood Area Network (NAN). However, the NAN data must be send through wider area cabled networks to Metropolitan Area Network (MAN), and based on the WDM-PON architecture. We consider a novel planning model which simultaneously solves both architectures and analyses the overall performance based on average packet delay.

The often unexpected load growth, failures of protection-related equipment and inadequate parameterization of protection functions make the analyses of protection events more complex and time-consuming. Besides, the amount of information that can be retrieved from modern digital relays is constantly increasing. In order to aid a quick decision-making and maintenance practices, this project aimed to implement a complete diagnosis system that is automatically activated whenever a protection-related event occurs. It covers the automation of the analysis system and the analysis system itself, which uses an expert system to process the data. It was important to observe that it is able to analyze different data sets in order to ensure the delivery of a report even when not all the expected input data is available. The system was successfully installed in a distribution substation of a Brazilian power distribution utility.

The paper analyzes the profitability for a wind farm of 50 MW, which marketed its energy on the Spot market, taking into account the current conditions of evolution of demand and the Uruguayan energy system. For a system with a high component of installed capacity of hydropower origin, the marginal cost is strongly affected by water availability conditions, which is a considerable risk for the wind energy investor. In addition the income may be affected by the entry into service of a second wind farm with similar characteristics, which will result in a decrease in the marginal cost of the system, adversely affecting revenues of the already installed parks which they market their power on the Spot market. Simulations with the software SimSEE, for a term of 20 years, allow one to estimate the generation of a wind farm of these features, as well as the evolution of the marginal cost of the system.

We subject a previously presented client-server allocation algorithm to a revised performance criterion to account for non-linear cost functions. We identify the conditions under which the original approach is not guaranteed to outperform the benchmark approach and propose a revised cost prediction method to improve performance for those scenarios. We present empirical results to show the measured benefit of the revised approach over the benchmark as well as the original work.

The expansion of distribution systems is up including distributed generation (DG). This alternative offers technical and economic benefits, but to reach them is essential unifies it, since, considered individually and independently, does not offer any benefits. This research proposes a new technique where DG is treated as an Equivalent Generation Unit (EGU), which will integrate the DG electrical grids. It is suggested that the EGU is structured as an intelligent generation system to improve the efficiency of DG and its performance within the grids. Shown are the results of applying this technique a test system consisting of three feeders.

This paper presents an approach to assess automatic fault location methods in power distribution systems. The proposed approach allows to consider the aleatory errors inherent to calculated, forecasted and measured values, typically required by the fault location methods for a more realistic and consistent evaluation. These errors can follow different mathematical distributions, according their source and the assumptions made. In order to demonstrate the proposed approach, a real power distribution system is considered, and additionally, one method that requires measurements at the power substation and one method that requires sparse voltage measurements are assessed.
