With the continuous increase of energy demand along with the congested transmission systems, distributed generation (DG) is suggested as a possible solution. In addition, with the limited fossil energy resources, the need for sustainable and environmentally friendly energy sources is increased. Energy hubs as one type of DG, have made the local use of multi energy carrier systems economically attractive...
In this paper, we study the energy storage management of microgrids with combined heat and power (CHP) co-generator and renewable energy. There are two kind of demands in the microgrid, power demand and heat demand. The power demand can be satisfied by the electricity from grid, CHP co-generator, renewable energy and battery; The heat demand is meet by the natural gas, CHP co-generator and the thermal...
The fight against climate change and the high import dependency on fossil fuels has led the European Union (EU) to a reinforced renewable energy strategy. Primary aims till 2020 are to reduce CO2-emissions about 20%, to increase the share of renewable energies to 20%, to improve the energy efficiency about 20% and to use about 10% of biofuels. In order to fulfil these ambitious targets especially...
At the authors institute a novel concept, the so called Energy Hub, was developed to solve optimal power flow (OPF) problems for integrated energy systems with multiple energy carriers. This paper applies the Energy Hub model on an OPF problem considering multiple renewables in a mixed-consumer area. From the experiences of a case study the following modifications of the general model were derived:...
