In the near future, notion of integrating distributed energy resources (DERs) to build a microgrid will be extremely important. The DERs comprise several technologies, such as diesel engines, micro turbines, fuel cells, photovoltaic, small wind etc. coordinated operation and control DER together with controllable loads storage devices, flywheels, capacitors batteries, are central concept microg...

Distributed energy resources (DERs), which are characterized by small-scale power generation technologies to provide an enhancement of the traditional power system, have been strongly encouraged to be integrated into the smart grid, and numerous trading strategies have recently been proposed to support the energy auction in the emerging smart grid marketing. However, few of them consider the se...

Voltage unbalance has gained more attention due to a rapid increase in single-phase distributed energy resources (DERs) penetration compound with existing characteristics of low voltage distribution network. The purposes this article are summarise various techniques on compensation from three different strategies: (1) based passive approach and advanced power electronics; (2) Techniques three-p...

As the penetration of distributed energy resources (DERs) escalates in distribution networks, new network tariffs are needed to cope with this new situation. These tariffs should allocate network costs to users, promoting an efficient use of the distribution network. This paper proposes a methodology to evaluate and compare network tariff designs. Four design attributes are proposed for this ai...

M ICROGRIDS, in particular, and smart grids, in general, are new emerging power distribution infrastructures with prominent potentials among them are realization of demand response and efficient energy consumption, integration of distributed energy resources (DERs), and high-reliability electricity delivery. DERs encompass combined heat and power, small wind turbine, photovoltaic sets, heat or ...

The irregularity and randomness of distributed energy sources’ (DERs) output power characteristic usually brings difficulties for grid analysis. In order to reliably and deterministically evaluate intermittent distributed generation’s active power output, a credible capacity index for active distribution network (ADN) is proposed. According to the definition, it is a certain interval that the s...

This paper presents a new Hybrid Particle Swarm optimization with Time Varying Acceleration Coefficients (HPSOTVAC) and Bacteria Foraging Algorithm (BFA) namely (PSOTVAC/BFA) base fuzzy stochastic long term approach for determining optimum location and size of Distributed Energy Resources (DERs). The Monte Carlo simulation method is used to model the uncertainties associated with long-term load...

With large-scale integration of distributed energy resources (DERs), distribution networks have turned into active distribution networks (ADNs). However, management risks and obstacles are caused by this in due to renewable energy generation (REG) forecasting errors. In this paper, a day-ahead active power scheduling method considering REG forecast errors is proposed to eliminate the risks, min...

It now seems inevitable that power grids of the future will be massive stochastic networks whose nodes are themselves microgrids comprising generation and storage units, inverters and power conditioning elements, together with controllable aggregations of appliances and other load classes. There will be significant amounts of power coming from wind, solar, and cogeneration enabled by combined h...

As the penetration level of distributed energy resources (DERs) is increasing at distribution level, stakeholders are no longer pure consumers and they play a more active role. DERs can be used for transmission needs, technical impacts them may propagate to level. To unlock full benefits transmission-distribution coordination, this article proposes second-order cone programming (SOCP) based exp...
