This section shows the mathematical formulation represented by the P-graph model. As discussed in Section 2, the optimization is divided into two stages based on hourly.
[pdf] Yemen has recently experienced a severe power shortage, unable to meet the power needs of its population and infrastructure. In 2009, the installed power capacity was about 1.6 GW, while, in fact, the power supply gap was about 0.25 GW. The power development plan (PDP) forecasts and estimates the capacity demand. .
As mentioned earlier, according to the International Energy Agency, in 2000, oil made up 98.4% of the total primary energy supply in Yemen, while in 2017, oil made up about 76% of the total primary energy supply, and natural gas. .
Yemen had a strategy to develop and improve its electrical potential before the events of 2011. The Public Electricity Corporation is responsible. .
According to the latest report of the World Energy Statistics Review 2020, 84% of the world’s energy is still supplied by fossil fuels, while renewable.
