Peak-valley tariffs and solar prosumers: Why renewable energy …
In summary, the virtual price of energy storage use is set as E p s t − j = E p m + 0.01. To ensure that prosumers first sell electricity in the LEM before storing and then sending the excess to the grid, we set the virtual price of energy storage slightly lower than the feed-in tariff given by E p j − s t = E p s − g − 0.01.
