What is the prospect of energy storage frequency regulation in california

Can energy storage systems be used for frequency regulation service?

Market Participation of Energy Storage Systems for Frequency Regulation Service: A Bi-level Model Abstract:This paper examines the prospect of using the energy storage systems (ESSs) in the distribution network for frequency regulation service under the two-settlement market mechanism.

Should energy storage systems be regulated?

Energy storage systems play a major role in this regard. Available options for revised regulation —Ideally, connecting to the grid should imply a commitment to pay for all of the network costs caused. Let us consider, just as an example, a typical scheme for a private regasification facility.

Can energy storage services be integrated at different levels of electrical systems?

According to Medina et al. (2014), energy storage services can be integrated at different levels of electrical systems, in particular at generation, transmission, distribution, and customer level. However, the authors detected some limiting factors.

Can energy storage provide a large set of Energy Services?

With regard to market design, energy storage is allowed to provide a large set of energy services, according to relatively recent modifications of Californian power market. Currently, energy storage may be used for Daily, weekly, and seasonal arbitrage.

Should storage services be regulated?

Hence, markets rules should allow storage services to compete in a nondiscriminatory manner with other services (e.g., utility-scale storage vs. CCGTs). The second kind of regulatory challenge has to do with the regulation of energy networks, because storage services may avoid the use of “regulated” networks.

Do locational signals influence energy storage investment?

As in traditional power regulation commercial flows are decoupled from physical flows, cost socialization is a frequent characteristic of network tariffs. However, locational signals may play a relevant role to decide on investment in energy storage systems.
