LSCEs may not be able to consume all of the electricity generated by their PVs for most periods of the year [7] and they may then sell surplus electricity to the utility grid at a lower tariff. This not only affects the stability of the utility grid operation [8], but also means that the income of LSCEs from selling electricity is less than the price paid
