Integration of home photovoltaic generation into electricity tariff for load optimization

Abstract

In an electric power grid with a growing share of renewable sources a growing need to control the load on the demand side arises. A fast and effective measure are market-based time-variable electricity tariffs which reflect the load to energy supply ratio in the grid. These can be used for sot minimization leading to load shifting to low-load times. If the household is also equipped with a generation device as a solar panel, the feed-in tariff becomes important. This publication treats the calculation of an effective electricity tariff out of different tariffs for consumption and feed-in, taking the constraints of the generation device into account. This effective tariff is a means for a suitable visualizaiton and automatic load optimization.
