Energy storage systems: power grid and energy market use cases

Abstract

Current power grid and market development, characterized by large growth of distributed energy sources in recent years, especially in Europa, are according energy storage systems an increasingly larger field of implementation. Existing storage technologies, e.g. pumped-storage power plants, have to be upgraded and extended by new but not yet commercially viable technologies (e.g. batteries or adiabatic compressed air energy storage) that meet expected demands. Optimal sizing of storage systems and technically and economically optimal operating strategies are the major challenges to the integration of such systems in the future smart grid. This paper surveys firstly the literature on the latest niche applications. Then, potential new use case and operating scenarios for energy storage systems in smart grids, which have been field tested, are presented and discussed and subsequently assessed technically and economically.

Technical Potential of Buildings in Germany as Flexible Power‐to‐Heat Storage for Smart‐Grid Operation

“…Diverse criteria to compare different types of storage greatly help in assessment of the technical potential because P2H applications complement or compete with genuine grid storage P↔X, and help to identify ancillary services to which P2H/demand response appear to be tailor‐made . A priori criteria for participating in LM programs, such as minimum participation, required response time, interruption period, advance notification, and metering requirements, are discussed in the ONRL study for US markets, which refers to another study by the Brattle Group .…”

“…Capacity market assets, such as combined‐cycle gas turbines, as backup plants cause substantial partial loading and standby costs. Genuine power storage, that is, mechanical, thermal, or chemical bulk storage; flywheels; pumped hydro plants; or compressed‐air caverns, raise concerns about infrastructure and installation costs. Converting surplus electricity into something else (mechanical, potential, or chemical energy, that is, P↔X) and back to electricity when needed entails new conversion paths, including grid infrastructure and construction projects .…”

Economic, environmental and social aspects of buildings’ refurbishment – a case study

“…In accordance with today's requirements, buildings are increasingly using energy obtained from renewable sources, among which solar and wind energy are the leaders. The unpredictability and irregularity of obtaining energy from renewable sources results in intense development of the electricity storage technologies (Komarnicki, 2016). The combination of proper management of energy consumption, the use of renewable sources and the energy storage use leads to the development of distributed energy and the emergence of the smart grid areas.…”
