An automated smart-grid battery storage controller uses the following algorithm to manage system operations, but it does not make efficient use of selection structures.
1 WHILE (controllerActive = True) DO
2
3 RECEIVE gridDemand FROM GRID_SENSOR
4 IF (gridDemand > 50) THEN
5 SET batteryMode TO "Discharging"
6 END IF
7
8 RECEIVE batteryTemp FROM TEMP_SENSOR
9 IF (batteryTemp > 45) THEN
10 SET coolingFan TO "High"
11 END IF
12
13 RECEIVE stateOfCharge FROM SOC_SENSOR
14 IF (stateOfCharge < 20) THEN
15 SET lowPowerWarning TO "Active"
16 END IF
17
18 IF (gridDemand <= 50) THEN
19 SET batteryMode TO "Charging"
20 END IF
21
22 IF (batteryTemp <= 45) THEN
23 SET coolingFan TO "Low"
24 END IF
25
26 IF (stateOfCharge >= 20) THEN
27 SET lowPowerWarning TO "Inactive"
28 END IF
29
30 END WHILE
Write replacement code to control the battery operating mode (batteryMode) that would improve the efficiency of this algorithm.
