Novel Electricity Pricing Method Based on the Customers’ Risk Aversion Function

Electricity pricing approaches are generally categorized into flat-rate and dynamic pricing models. Flat-rate pricing charges a fixed rate regardless of market conditions, whereas dynamic pricing adjusts rates based on system and market factors. Traditional pricing methods often lack flexibility, preventing consumers from choosing their preferred pricing plans. This study introduces a Selective Electricity Pricing (SEP) model that allows customers to select a Maximum Tolerable Price (MTP) tailored to their needs and benefit from Real-Time Pricing. The SEP model also includes a retailer-funded mechanism to shield customers from high market prices, acting as a risk hedge. Using a risk aversion function to gauge consumer preferences, the SEP method was implemented on the IEEE-۲۴ test system. Results indicate that low-risk customers are more likely to engage in dynamic pricing. The SEP model significantly outperforms flat-rate pricing, yielding ۱۷.۲۷% higher retailer profits, ۱۱.۳۲% lower demand, and a ۲.۷۳% increase in average customer payments, compared to a ۲,۵۰۰MW drop under flat-rate pricing.
