“…Since 1982, the increase in peak electricity demand and electricity usage has increased from the growth in electric appliances and increasing demand of power by industry. The increase is almost 25% by each year according to the USA department of energy [4]. Moreover, considering the residential sector in the USA, the electricity sales are expected to increase 24% from 2011 to 2040 [5].…”

“…This dilemma can be solved by enhancing the existing transmission capability, decreasing peak load, increasing distributed generation and exploring new methods of energy generation such as renewable energy sources (RESs). Researchers are trying to expand traditional grid infrastructure to meet new challenges; however, it is a very expensive job [4].…”

With the emergence of the smart grid, both consumers and electricity providing companies can benefit from real-time interaction and pricing methods. In this work, a smart power system is considered, where consumers share a common energy source. Each consumer is equipped with a home energy management controller (HEMC) as scheduler and a smart meter. The HEMC keeps updating the utility with the load profile of the home. The smart meter is connected to a power grid having an advanced metering infrastructure which is responsible for two-way communication. Genetic teaching-learning based optimization, flower pollination teaching learning based optimization, flower pollination BAT and flower pollination genetic algorithm based energy consumption scheduling algorithms are proposed. These algorithms schedule the loads in order to shave the peak formation without compromising user comfort. The proposed algorithms achieve optimal energy consumption profile for the home appliances equipped with sensors to maximize the consumer benefits in a fair and efficient manner by exchanging control messages. Control messages contain energy consumption of consumer and real-time pricing information. Simulation results show that proposed algorithms reduce the peak-to-average ratio by 34.56% and help the users to reduce their energy expenses by 42.41% without compromising the comfort. The daily discomfort is reduced by 28.18%.

“…As supported from several references, EMTP-type tools can be used to analyze large-scale smart grids; see for instance [32,33]. Although the number of cascaded modules included in the present model for each single-phase SST branch is probably low, the performance with a higher number of modules per phase would be basically the same (except for the ripple exhibited by the primary side currents); the present representation can even be useful in the design of the SST.…”

This paper presents a time-domain model of a MV/LV bidirectional solid state transformer (SST). A multilevel converter configuration of the SST MV side is obtained by cascading a single-phase cell made of the series connection of an H bridge and a dual active bridge (dc-dc converter); the aim is to configure a realistic SST design suitable for MV levels. A three-phase four-wire converter has been used for the LV side, allowing the connection of both load/generation. The SST model, including the corresponding controllers, has been built and encapsulated as a custom-made model in the ATP version of the EMTP for application in distribution system studies. Several case studies have been carried out in order to evaluate the behavior of the proposed SST design under different operating conditions and check its impact on power quality.

“…However, the connection of generation to the distribution system can cause miscoordination of protection devices and, if not properly handled, reduce reliability and power quality. Although distributed generation is often presented as a solution for reliability improvement, the fact is that such assumption is not always accepted or supported, see for instance [3].…”

“…In the first case, the generation units are locally operated and can be allowed to inject power to the system; if they are correctly controlled, they can have a positive impact on distribution system reliability [4]. A generation unit operating in parallel to the system can be forced to be disconnected in case of system fault, so the benefit to the system reliability can be negative [3,4]. This paper presents an expanded version of a procedure for reliability of distribution systems developed by the authors and presented in [5].…”

This paper presents a Monte Carlo approach for reliability assessment of distribution systems with distributed generation using parallel computing. The calculations are carried out with a royalty-free power flow simulator, OpenDSS (Open Distribution System Simulator). The procedure has been implemented in an environment in which OpenDSS is driven from MATLAB. The test system is an overhead distribution system represented by means of a three-phase model that includes protective devices. The paper details the implemented procedure, which can be applied to systems with or without distributed generation, includes an illustrative case study and summarizes the results derived from the analysis of the test system during one year. The goal is to evaluate the test system performance considering different scenarios with different level of system automation and reconfiguration, and assess the impact that distributed photovoltaic generation can have on that performance. Several reliability indices, including those related to the impact of distributed generation, are obtained for every scenario.
