Reactive power compensation and energy storage

How to reconfiguration a distributed power network and reactive power compensation?

Conclusion The paper addresses the topic of reconfiguration of distribution power network and reactive power compensation, taking into account the presence of distributed energy sources and storage systems. The reconfiguration is performed by Minimum Spanning Tree, Kruskal algorithm, followed by capacitor switching by Simulated Annealing.

What is reactive power compensation?

It was initially decided that the size of reactive power placed at each wind turbine should be equal to the reactive power required during no load (no wind). The most common reactive power compensation is a fixed capacitor. The inclusion of reactive power compensation using SVC installed at Bus 40 was an improvement to the previous systems.

Why do wind farms need energy storage and reactive power compensation?

Because the loads and the wind farms' output fluctuate during the day, the use of energy storage and reactive power compensation is ideal for the power system network. Energy storage and reactive power compensation can minimize real/reactive power imbalances that can affect the surrounding power system.

What is reactive power compensation & energy storage in Tehachapi wind farms?

As wind power generation in the area continues to expand, reactive power compensation and energy storage will be required. reactive power compensator is a very important aspect of wind generation in the Tehachapi wind farms. Most of the wind turbines currently operating in the area are induction generator wind turbines (constant frequency).

What is active power compensation?

Active power compensation. The maximum active power provided by the BESS is 20 kW. So, a quantity of reactive power is available to be used. Indeed the control system can use that reactive power and the result is shown in Fig. 17. Fig. 17 shows as the reactive power requested by the EV fast charge can be provided by the BESS.

Do dynamic active and reactive power compensation improve electrical performance?

In general terms, we can affirm that for both test systems, the dynamic active and reactive power compensation from batteries improve the electrical performance of the ac network when higher variability of renewable generation and power consumption are considered under an economic dispatch environment.
