Wind energy conversion systems are now occupying important space in the research of renewable energy sources with microgrid. The main challenge in wind power generation is power quality problem and their connection with the distribution network in microgrid. The main factor behind poor power quality is the impact of harmonics in current and voltage in power network. In microgrid the converter a...

Microgrids have a long history. In fact, Thomas Edison‘s first power plant constructed in1882 – the Manhattan Pearl Street Station – was essentially a microgrid since a centralized grid had not yet been established. By 1886, Edison‘s firm had installed fifty-eight direct current (DC) microgrids. However, shortly thereafter, the evolution of the electric services industry evolved to a state-regu...

A microgrid is an eco-friendly power system because renewable sources are used as main power sources. In the islanded operation mode of a microgrid, maintaining the balance between power supply and power demand is a very important problem. In the case of surplus supply, decreased generation output and/or charge of distributed storages can be applied to solve the imbalance between power supply a...

This paper presents an optimal scheduling model for a microgrid participating in the electricity distribution market in interaction with the Distribution Market Operator (DMO). The DMO is a concept proposed here, which administers the established electricity market in the distribution level, i.e., similar to the role of Independent System Operator (ISO) in the wholesale electricity market, sets...

This paper presents a novel use of the HOMER Software for multi-year economic, environmental, and energetic assessment proposed multi-source standalone renewable microgrid. A rural-but-rapidly-commercializing community in Nigeria's middle belt was used as case study, with an average power demand 975 kW consumption 23.028 MWh/day. generation mix flat-plate photovoltaic (PV) array (3 MW nominal),...

Abstract The microgrid dominated by new energy has small inertia and weak damping, while a virtual synchronous generator (VSG) is an effective means to enhance damping improve the stability of microgrid. However, it also introduces power angle oscillation problems similar that machines. This paper based on current inner loop voltage outer control three-phase LCL inverter. It coefficient generat...

Renewable and non-conventional distributed energy resources (DERs), such as, wind, solar PV, micro-turbines, fuel cells, diesel generators etc. are gradually becoming more popular as energy efficient and low-emission energy sources. Demand-side management, along with the integration of distributed energy generation and storage, are considered increasingly essential elements for implementing the...

In carrying out the planning of energy operation an electrical system, it is sought to establish participation each generating unit in order ensure supply demand at lowest possible operating cost, respecting technical restrictions. this sense, Dynamic Programming (DP) method, widely used electricity sector, presented determine optimal dispatch units, observing factors such as cost and maximum p...

This paper presents the importance of deployment of distributed energy resources as a promising aspect which is emerging as a future power system as microgrid in the power community worldwide. The basic concepts of microgrid technology including its operational and control techniques are presented briefly in simplified manner. The application and prospect of microgrid in Indian power scenario a...
