Battery load compensation

Optimization-based power management for battery

As expected, the proposed method faces a 1% reduction in capacity after 46 times load compensation. In contrast, with the filter-based and droop control, this happens after 24 times, and with the fuzzy method after 21 times. This means improving the battery health by almost 50% compared to other control methods under the mentioned load profile.

6 FAQs about [Battery load compensation]

What are the cost functions of a battery?

Consequently, two cost functions are considered for the battery; minimization of the battery charge current changes (same as deficit power mode in Eq. (20)), and bringing the battery current to the standard battery charge current (ich,std) recommended by the manufacturer. (36) f b, s t d = 1 - r 2, r = 1

How to optimize power allocation between battery and SC?

In order to optimize power allocation between the battery and SC, the exact load current must be known to PMS. As mentioned, in some applications like EV, using additional sensors, the load current can be measured. However, in microgrid applications, more than loads, generation units, and other ESSs exist.

Why do battery and SC participate in grid excess and deficit power modes?

So, both the battery and SC would participate in grid excess and deficit power modes. Due to the microgrid application, the bus voltage is regulated at the desired value by proper control of the SC current. The adaptive Kalman filter is used to estimate the grid required current by use of DC-bus voltage deviation.

Does dynamic reactive power compensation reduce operative cost?

The inclusion of the dynamic reactive power compensation with batteries reduces the total operative daily cost for both test feeders in 25.6223% and 14.9347% for the 33- and 69-node test systems, respectively; which implies 2.2534% and 2.7242% of additional improvement when reactive power capabilities of the VSCs are used. 5.2.2.

What happens when a battery reaches a voltage threshold?

When the system detects that the battery voltage reaches voltage threshold, it will switch to CV mode for charging automatically. In CV mode, the load impedance is gradually increasing while the charging current of the battery is gradually decreasing. Figure 17b analyses the efficiency and power of the system during battery charging.

What does CC/CV mean in battery charging?

When the resistance value is 8 Ω, the current is constant around 1.6 A, and the efficiency is close to 88%. The performance in CC/CV mode. (a) The outputted voltage and current during the battery charging. (b) The system efficiency and transmitted power in the process of charging. CC, constant-current; CV, constant-voltage.
