The Balance of Power System Peak Load Regulation Considering the Participation of Nuclear Power Plant

Abstract

Nuclear power plants (NPP) have to face urgent requirement of participating in peak load regulation of power grid. The peak load regulation performances of NPP were researched. Based on the calculation and analysis on peak load regulation cost and benefit of NPP, the location, criterion and peak balance algorithm of NPP participating in peak regulation were proposed. Results of the actual research show that NPP possesses better ability of peak load regulation and the cost is lower, so NPP can participate in daily peak load regulation, which will improve both security and flexibility of power grid and enhance the efficiency of resource configuration. However, the depth and speed of peak load regulation by NPP are restricted by security and economy.

A multi-objective formulation of improving flexibility in the operation of electric power systems: Application to mitigation measures during the coronavirus pandemic

“…When the nuclear source is an important share of the energy matrix, it is essential to improve the load following capacity. PWR reactors are very widespread at a global level and they can regulate their range up to 5% of the nominal output per minute [ 27 ]. As a result, nuclear plants operate three modes (depending on their type): base-load mode (modeled in (7), where is the rated power for a nuclear generator), frequency control mode [ 28 ], and load following.…”
