Notes on energy storage grid dispatching and operation

Can battery energy storage systems support renewable DG in distribution networks?

With the rapid development of distributed generation (DG), battery energy storage systems (BESSs) will play a critical role in supporting the high penetration of renewable DG in distribution networks. The traditional dispatching approach of BESSs commonly adopts linear models with constant operational characteristics and neglects the aging cost.

Why are battery energy storage systems used in microgrids?

Hence, battery energy storage systems (BESSs) are widely used to balance the power and shave peaks in microgrids . Furthermore, BESSs can be scheduled to increase the electricity revenue for microgrid entities by charging energy in low-price periods and discharging energy in high-price periods .

How to manage energy storage in a microgrid?

Managing energy storage in microgrids: a multistage stochastic programming approach When edge computing meets microgrid: a deep reinforcement learning approach Reinforcement learning approach for optimal distributed energy management in a microgrid Dynamic pricing and energy consumption scheduling with reinforcement learning

Why is energy storage important to the grid?

These storage systems have provided a wide range of services to the grid including load balancing, load following, reserve generation, and frequency and voltage support. With increased penetration of variable generation like solar and wind, there will be higher demand for such services, therefore energy storage will become critical to the grid.

What drives grid-level energy storage?

The drivers for grid-level energy storage are rapidly decreasing cost of energy storage, and the multitude of benefits provided by energy storage to the grid in general and to grids with high penetration of renewable energy in particular. The rapid decrease in cost is primarily driven by rapid innovation and scale in the electric vehicle market.

How can a microgrid reduce power fluctuations?

1. Introduction 1.1. Background Volatile energy resources, such as loads from renewable energy based distributed generators (DGs) and electric vehicles (EVs), significantly affect the operation of power systems. In microgrids, we can coordinate volatile energy resources and energy storage to mitigate power fluctuations .
