Photovoltaic panels utilization as a solution for consumers in the residential sector to dynamic pricing scenario

Dynamic pricing of electricity is an electricity tariff system that changed according to the load demand on that particular time. In general, electricity price will be more expensive at night when the load demand is at its highest and cheaper when the demand is at its minimum. From a consumer standpoint, dynamic pricing will cause a large increase to their electricity bills. A system with renewable electricity generator is one of the method to answer this problem. By using generation component such as a solar panel, the consumer can use the generated energy during the daytime or storing it in a storage component like a battery to use it in peak-time when the tariff is much higher. Even more so, the excess energy from solar panel can be sold to the grid to reduce the spending on electricity bills. This experiment will discuss how big is the effect of the aforementioned system in the dynamic pricing scheme by using HOMER simulation. By using photovoltaic panels and batteries, every IDR 100/kWh of export price reduction resulting in profit increase by IDR 5.000.000/kWh for a project lifetime of 25 years. Even more so, every IDR 100/kWh of import price addition could increase the profit by IDR 30.000.000/kWh for a project lifetime.
