Paper on "Deployment and Operation of an Isolated Smart Grid"

Paper on "Deployment and Operation of an Isolated Smart Grid"

A paper* to be presented at the 35th International Telecommunications Energy Conference   Summary / Abstract This paper presents the design, deployment and operation of an isolated smart grid in Xanthi, Greece. The overall topology and the architecture of the grid is analyzed, including the power production, transmission, consumption and the communication infrastructure. The grid consists of three smaller microgrids that are connected together through a common DC bus. Each microgrid consists of equipment exploiting various renewable energy sources, a local load, a battery and a diesel generator. In the third microgrid, hydrogen is also utilised by a long term energy storage facility. A case study shows that when the three microgrids are connected allowing energy exchange among them, the overall efficiency is greatly increased as the usage of the diesel generators is reduced and the available energy is fully exploited.   1. Introduction Traditional power grids consist of four distinctive components: generation-transmission-distribution-consumption. The energy flow is unidirectional from the few central power generation stations to the consumer. This topology suffers from three main problems; the efficiency significantly drops due to losses during the transmission stage, the grid is not designed for equipment facilitating distributed generation such as Fuel Cells (FCs) and Photovoltaic panels (PVs), while the effects of locally observed malfunctions or other similar problems are easily propagated throughout the entire grid [1]. For this reason, an information grid is placed on top of the power grid and with the use of modern power electronics; energy and information can easily be transmitted in multiple directions within the grid [2]. Thus, it is possible to use distributed sources for... read more

Box 60361, 57001, Thessaloniki, Greece Systems Sunlight S.A., Neo Olvio, 67200 Xanthi, Greece Department of Automation, Alexander Technological Educational Institute of Thessaloniki (ATEITH), P.O. Box 141, 54700, Thessaloniki, Greece Abstract The core aim of the presented study, is the analysis, development and implementation of an integrated control framework for the on-line energy management of an autonomous hybrid solar-wind stand-alone system. The systemic development of the power management strategy (PMS), is based on a novel and flexible methodology that enables the concurrent handling of the subsystems interactions. The hybrid system is installed at the premises of Systems Sunlight S.A. in Neo Olvio, Xanthi and meets a few kW variable load demand. The operation of each subsystem is managed by a Supervisory Control and Data Acquisition System (SCADA) that allows remote monitoring and control. Introduction The use of renewable energy sources (RES) for the production of electrical energy can contribute significantly to the reduction of greenhouse emissions and protect the sensitive environment from further degradation. Solar and wind energy are considered an excellent choice in stand-alone applications, since they are abundant, free, clean and inexhaustible. Nevertheless, the wide fluctuation of climate data requires the utilization of storage systems in the forms of lead-acid accumulators (short-term) and hydrogen production/utilization units (long-term). Through such an approach system autonomy is improved, shut-downs due to power deficiency are minimized, while system flexibility is maintained at a higher level. The aim of this work is to... read more
