The steady rise of the integration of renewable energy sources (RES) has led to a re-examination of existing energy storage technologies as well as the development of new ones, e.g. power-to-gas (P2G) technology. This technology uses surplus of electricity from RES to create the synthetic natural gas, which can be stored for long periods of time, and thus it can significantly support the integration of RES into the existing power grid and extend a system transmission capacity, which is needed because of increasing number of volatile renewable resources. This paper gives an overview about the main aspects of the P2G technology. In the scope of this study the selection of optimal installation points for such a technology - depending on different criteria (e.g. availability of RES, gas network, renewable CO2) - is described. The case study is based on the German federal state Saxony-Anhalt, which plays a leading role in Germany for the renewable energy production and is the largest exporter of electricity and importer of natural gas. The P2G technology implementation makes it possible to increase the security and autonomy of supply security and autonomy for the chosen region
The objective of this study is to analyze the influence of electrochemical energy storage systems on low voltage grids with high penetration of renewables (RES), mostly photovoltaic power stations (PV). Furthermore, it compares the integration of energy storage systems (ESS) with other alternative solutions economically. It also presents the simulation results for a German power network in a suburban area of Bavaria. In the case study, the ESS are used to reduce overloading of electrical equipment (e.g. power cables and transformers) caused by fluctuating generation of integrated RES. The simulation results reveal that economic use of energy storage to support the grid is feasible when it is accompanied by a specific incentive. The storage tariff necessary for this is comparable with the initial Renewable Energy Act tariff for renewables, thus making this a realistic method for facilitating the use of EES that benefits the grid
The price of electricity is rising steadily. Due to this fact, efficient energy usage, especially in the highly complex energy infrastructures, plays a very significant role. An Energy Management System (EMS) can provide the solution for energy and costs saving. This paper presents the description of a Dynamic Energy Management System (DEMS) which was applied to a complex building infrastructure. The main focus of this study is related to a strategy for optimizing the energy consumption within a building structure and to improve the overall energy efficiency of the micro system
