Formulation of maximum voltage index for power distribution system containing grid-connected photovoltaic system

Solar energy is one of the favourite renewable energies in Malaysia due to its relatively consistent power generation throughout the year. The solar panel price drops drastically compared to the last few decades, making it affordable to the public. In Malaysia, the government has introduced Feed-in-...
