As the integration of Distributed Energy Resources (DERs) in modern grids is increasing, the microgrid concept has been established. In the case of converter-dominated microgrids without communication links, the droop control method is mainly adopted in the primary control level. Normally, the economic operation of the microgrid is incorporated in the secondary control level, requiring communic...

A rapidly growing amount of small-scale distributed energy resources (DERs) integrated into distribution systems call for an effective electricity market to manage the uncertainty DERs and remove barriers participation in wholesale markets. To this end, paper proposes uncertainty-aware locational marginal pricing (DLMP) mechanism based on robust optimization day-ahead markets within a transmiss...

It is possible to notice the growing increase in insertion of Distributed Energy Resources (DERs) Brazilian distribution system. Thus, this article aims analyze impact allocation and optimal sizing photovoltaic plants battery banks through Bat Algorithm optimization method. This simulation proposes a minimization technical losses voltage unbalance, moreover, simulations were performed using Ope...

Curbing incessant and erratic power supply to halls of residence within the University of Ibadan Campus has been an impetus that has led to an upsurge in the number of proposals all geared towards providing solution to this critical problem. One of such proposals opines the design of a virtual power plant (VPP). In proposing such, the author seeks to address the problem on a double approach – t...

Power quality (PQ) disturbances are becoming an important issue in smart grids (SGs) due to the significant economic consequences that they can generate on sensible loads. However, SGs include several distributed energy resources (DERs) that can be interconnected to the grid with static converters, which lead to a reduction of the PQ levels. Among DERs, wind turbines and photovoltaic systems ar...

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...

The microgrid concept is a natural evolution of distributed resources that may be used to serve energy to customers in areas where conventional power system approaches cannot satisfy the reliability needs. Microgrids[2] may also provide support to conventional power systems that are too constrained to meet the power demands of customers. This paper presents a case study of a remote village depe...

Due to the growing number of distributed energy resources (DERs) and new loads, such as electric mobility, distribution system operators (DSOs) are facing an increasing complexity. Manual processes based on basic planning principles are confronted with new and potentially cost efficient technology options in the context of smart grids. These smart grid options comprise voltage regulating assets...

The active participation of demand-side flexible resources in the wholesale market price formation and load dispatch process is crucial to encouraging participation. This calls for a joint supply-demand coordination mechanism fully take advantage distribution systems, including distributed energy (DERs) responsive loads (RLs). paper aims at comparing evaluating centralized transactive distribut...
