Operation of energy storage power plant

How do energy storage stations work?

In this mode, new energy power plants form a consortium to jointly invest in and build an energy storage station. Once the energy storage station is constructed, it operates as an independent entity, serving multiple new energy power plants that participated in the investment.

What is shared energy storage?

In the shared mode, the energy storage is collectively owned by a consortium of new energy power plants, with the individual plants within the consortium serving as the users. Due to these differences in ownership and usage rights across the modes, the energy storage configuration schemes also differ.

Why do new energy power plants need energy storage?

Due to the uncertainty in the output of new energy power plants, there is a phenomenon of power curtailment during actual output. By configuring energy storage, new energy power plants can store the excess energy and discharge it when the output is insufficient, thus compensating for the power deficit.

What are battery storage power stations?

Battery storage power stations are usually composed of batteries, power conversion systems (inverters), control systems and monitoring equipment. There are a variety of battery types used, including lithium-ion, lead-acid, flow cell batteries, and others, depending on factors such as energy density, cycle life, and cost.

Which energy storage mode is best for new energy plants?

Despite the extensive research on energy storage configuration models, most studies focus on a single mode (such as self-built, leased, or shared storage), without conducting a comprehensive analysis of all three modes to determine which provides the best benefits for new energy plants.

What is a pumped storage power plant (PSPP)?

Another challenge in the power system operation with a high share of intermittent RES is the curtailment problem in the case of an excess of supply when conventional generators cannot reduce their output due to technical constraints . Pumped storage power plants (PSPPs) present a proven technology to mitigate these effects.
