The aim of this paper is to provide a concept for an information modeling method for micro grids, which will be used as building blocks for a smart grid. The data modeling method utilized is based primarily upon the IEC 61850 communication protocol standard. The article points out several useful features of the IEC 61850 communication protocol, the virtual information model and the communicatio...

This paper presents the simulation technique for simulating a micro grid (MG) and the analysis results of the operating characteristics of a MG with a hybrid power source. The hybrid power source in this research included both a diesel engine generation set and a wind generation system. The simulation tool adopted by this research is the professional software, Simulink. The simulation results a...

This paper covers the development of a new smart distributed DC Micro-grid system, especially in rural areas in order to utilize energy available from distributed, renewable generators. The proposed DC micro-grid system is hybrid in nature and it utilizes the proper use of renewable as well as fossil fuel resources. It is normally fitted for residential and small commercial applications as well...

Maximum power point tracking (MPPT) of a photo voltaic system with different temperature and insolation conditions used for Micro grids can be explained in this paper. The micro grid conception permits small distributed energy resources (DERs) to act during a coordinated manner to produce a necessary quantity of active power and supportive service once needed. This paper proposes an approach of...

For the management of a (micro)-smart grid it is important to know the patters of the load profiles and of the generators. In this article the power consumption data obtained through a monitoring activity developed on a micro-smart grid in an agro-industrial test-site are presented. In particular, this reports the synthesis of the monitoring results of 5 loads (5 industrial machineries for crop...

The traditional approach in electric generation is focused on centralized plants producing electricity which is transmitted and distributed over long distances through the networks. In contrast, using distributed energy resources, much smaller amounts of energy are produced by numerous small, modular energy conversion units, which are often located close to the point of use. Therefore, Distribu...

In this paper, a renewable energy integration facility (REIF) with photovoltaic (PV) distributed generation resources for micro-grid applications is studied. In grid-tied operation, the PV system together with the grid supply the power to the local loads while the surplus energy is fed back to the grid. In stand-alone mode, a gas micro-turbine is operated as a master to establish the common AC ...

The demand for high quality electricity and growing electricity consumption has been caused by increasing electrification of daily life causes and the rising number of sensitive or critical loads. Due to the rapid increase in global energy consumption and the diminishing of fossil fuels, the customer demand for new generation capacities and efficient energy production, delivery and utilization ...

E-mail address: [email protected]; [email protected] Abstract This article presents the development of an optimized droop controller of microgrid during islanding using artificial fish swarm algorithm (AFSA). This is necessary in order to minimize the frequency deviation that occurs when microgrid switches to stand-alone mode or when there are changes or variation in loads. The optimize...

The need of reducing CO2 emissions in electricity generation field for solving global warming problems have led to increase the interest in Micro-Grid (MG) especially the one which included renewable sources. MG normally operates in normal interconnected mode and connects with the main grid. When a large disturbance happens in main grid, MG transfer to islanding mode. This paper deals with conn...
