Magic Bus: High-Voltage DC on the New Power Transmission Highway

Abstract: The interconnected electric power grid is the single largest and most complex machine in the world. Power outages, even for a short interval, have a very low probability but an enormous impact. Transmission systems around the world are facing increasing load demands, and system elements are being pushed toward their thermal limits. Wide-area power trading with varying supply and load patterns is contributing to the ever-increasing congestion. The power grid of the future must be secure, cost effective, and environmental friendly yet reliably integrated and built with intelligent solutions and innovative technologies. High-voltage dc (HVDC) transmission systems are a proven tool in tackling these challenges.

Modelling and power quality analysis of a grid-connected solar PV system

Abstract: Increased concern about global warming coupled with the escalating demand of energy has driven the conventional power system to be more reliable one by integrating Renewable Energies (RE) in to grid. Over the recent years, integration of solar PV forming a grid-connected PV is considered as one of the most promising technologies to the developed countries like Australia to meet the growing demand of energy. This rapid increase in grid connected photovoltaic (PV) systems has made the supply utilities concerned about the drastic effects that have to be considered on the distribution network in particular voltage fluctuations, harmonic distortions and the Power factor for sustainable power generation. However, irrespective of the fact that the utility grid can accommodate the variability of load or irregular solar irradiance, it is essential to study the impact of grid connected PV systems during higher penetration levels as the intermittent nature of solar PV adversely effects the grid characteristics in meeting the load demand. Hence, keeping this in track, this paper examines the grid-connected PV system considering a residential network of Geelong region (38°.09'S and 144°.21' E) and explores the level of impacts considering summer load profile with a change in the level of integrations. Initially, a PV power system network model is developed in MATLAB/Simulink environment and the simulations are carried out to explore the impacts of solar PV penetration at low voltage distribution network considering power quality (PQ) issues such as voltage fluctuations, harmonics distortion at different load conditions.

Apparatus and method for controlling supply and demand of micro-grid

Abstract: PROBLEM TO BE SOLVED: To provide a supply and demand technique of a micro-grid, which is capable of improving the stability in frequency of the micro-grid in a power unserved area or an isolated island. SOLUTION: The micro-grid 100 connects a recycle energy utilizing power generating facility 150, and an internal combustion power generating facility 130 for compensating the facility 150 and a power storage device 140 to a power transmission network 110 and supplies power to a load 120. The micro-grid executes power supply and demand control while maintaining a stable system frequency f by adding control using the system frequency f by a load frequency control unit 240 and an interlinking line flow ΔP T to the control of an internal combustion power generator output 231 and a storage battery output 232 by a predictive function unit 210, a supply and demand scheduling unit 220 and an economic load distribution control unit 230.

Heat/electric power supply system having power storage unit

Abstract: A heat/electric power supply system having a power storage unit the entire efficiency of which is enhanced while reducing the capacity of a facility. The heat/electric power supply system having a power storage unit is characterized in that electric power is supplied from a generator, a commercial power supply and the power storage unit in a time zone where the power consumption by a power load is higher than a specified output C1 and commercial power is stored in the power storage unit in a time zone where the power consumption by the power load is lower than a specified output C2. Since commercial power stored in the power storage unit in the night time zone can be utilized at the time of peak power demand, the backup power at the time of peak power demand can be reduced.

Virtual power plants, real power

Abstract: The Danish island of Bornholm, a quiet farming and fishing community of 42,000 in the Baltic Sea, will soon be home to one of the world's smartest smart grids. Through the four-year, €21 million (US $28 million) EcoGrid project, about 2000 households there will be connected to an islandspanning network that will enable homeowners to cut back their electricity usage at times of peak demand and sell that unused wattage back to the grid at market rates. Managing all of these thousands of discrete energy trades, as well as Bornholm's other power resources- including 36 megawatts of wind power, a 16-MW biomass plant, and a new fleet of electric cars-will be a central control system that behaves very much like a traditional power generator. Only this generator will be created entirely through software-a virtual power plant.
