Abstract. Local energy markets are a promising way to involve prosumers in the electricity system and activate demand-side flexibility. In this paper, we develop a modeling framework consisting of an optimization for prosumer home energy management systems embedded in a local energy market simulation.
Among other options, electricity storage plants, i.e., systems that buffer energy and that are bidirectionally coupled with the power system, can provide flexibility. Storage systems can be employed for different applications, which can be categorized in energy, grid, and reliability services.

Schwerin Battery Park. Description. In order to store the excess wind energy in the region, the 5MW/5MWh battery park was installed in the city of Schwerin (Germany), consisting of 25,600 lithium manganese-oxide cells supplied by Younicos and Samsung SDI. In late 2016, WEMAG decided to enlarge their battery park.
This paper focuses on the economics of energy storage participating in arbitrage and regulation services within different markets. A case study on gravity storage system is used to verify the effectiveness of the proposed operation optimization model. Finally, this paper discusses the value of storage in various grid applications.
Development history. The development of energy storage in China has gone through four periods. The large-scale development of energy storage began around 2000. From 2000 to 2010, energy storage technology was developed in the laboratory. Electrochemical energy storage is the focus of research in this period.
