Introduction

This is the final result, the simplest energy management strategy, rule-based, simulated for an entire year. Electricity costs have dropped by about 6%, but look at the battery SOC, it's almost always empty exactly when the tariff is the highest. Let's start. Hello, welcome to episode three of the microgrid energy management series based on MPC. Most commercial hybrid inverters use simple rules. Store surplus in the battery, use the battery when there's a shortage, and the rest from PLN. Today we are writing this strategy, making it a benchmark, and finding its weaknesses.

Step 1: Charging and Discharging Rules

Create a file named rule-based.py The cost function calculates the total purchase from PLN multiplied by the purchase price, minus the sales multiplied by the selling price. The rule-based simulation function runs hour by hour, and the net load is directly given to the battery. If the net is positive, the battery discharges, if negative, the battery charges, of course limited by the battery model. The remaining energy that the battery cannot handle becomes import or export to PLN.

Step 2: Annual Cost

Now let's compare it with the condition without a battery. Run Without a battery, electricity costs for a year are about Rp 299.5 million. With rule-based, about Rp 281 million, saving 6.2 percent. Import from PLN is 255 MW hours, and the battery moves 60 MW hours of energy. But notice, 67 MW hours of import occurs during WBP, the most expensive hours.

Step 3: SOC at Peak Load

Let's look at August 1 Week. The top graph, the battery discharges whenever there's a shortage, including the morning when the tariff is still low. The bottom SOC graph, with red marks as WBP hours. SOC is almost always at the lower limit of 20% when entering WBP, because the energy has already been used earlier, and the battery is only charged from rare surplus PV. This rule does not know the future and does not know the price.

Done!

Done. We have already written the rule-based strategy, simulated it for a year, calculated the cost and savings, and found its weakness during peak load hours. In the next episode, we formulate a model predictive control that considers forecasts and prices.
