Power-based distribution tariffs for residential customers – A risk for overloading of network in areas with high penetration of Time-of-Use DSO tariffs?

Abstract

Finnish distribution system operators (DSO) have had to provide customers distribution tariffs with different prices on different time of uses (TOU). When electricity system is developing from centralized production and consumption customers to decentralized prosumer customers and multidirectional power flows, traditional tariff systems do not incentivize to overall efficient use of capacity and resources.This paper focuses on studying effects of present nighttime tariff customers’ load control actions on distribution grid loads. The network analysis is performed on secondary transformer level with real hourly customer load demand data.
