Study on the Evolutionary Trend of Grid Functionalized Investment Structure under Composite Scenarios

The construction of the new power system has accelerated the evolution of the structure, technology, and functions of the power grid. This expands the functions of power grid investment. Managing the grid investment requirements by functions is more necessary accounting for the investment structure optimization purpose. This paper applies a system dynamics model to analyze the functional demand for power grid infrastructure investment. The evolution trend of power grid investment is clarified through evaluating the construction scale. A power grid investment demand model is proposed to meet both the load growth and the new energy supply growth coming with the energy structure transformation.
