Research on New Energy Integration Capacity in Power Grid

Abstract:

Due to their high inter-temporal variation and intermittence, large-scale integration of the new energies, such as wind power and photovoltaic power, will pose great challenges to the safe and stable operation of power system. Analysis on gird stability and adaptability before integrating the new energy should be made. The paper investigates all kinds of restrictions and assesses each constrained capacity from the perspective of steady-state and transient voltage, frequency stability, cross-section transmission limit and peak load regulating capacity, respectively. Then the comprehensive evaluation on the capability to accommodate new energy for a power grid is accomplished. Take a practical grid for example, its accommodation capacity for new energy is calculated based on the above-mentioned method, which provides a theoretical basis for the grid to accommodate new energy and planning and construction of new energy.
