Base on Nuclear Power Plant (NPP) participating in peak load regulation of power grid, this paper studies the operation mode of hydropower, thermal power and NPP in Combined Peak Load Regulation. The optimization model for Peaking depth of NPP was set up. The case based on actual power grid were calculated and analyzed, results of the research show that in combined peak load regulation of hydropower, thermal power and NPP, a reasonable peaking depth of NPP will effectively alleviate the peaking pressure of power grid, avoid start-stop of thermal power and abandoned water of hydropower, while ensuring the hydroelectric generating capacity in the low load periods, and ensure thermal power output smooth, it further reduce the operating costs, verify the effectiveness of the model.

In this paper, the hourly demand response (DR) is incorporated into security-constrained unit commitment (SCUC) for economic and security purposes. SCUC considers fixed and responsive loads. Unlike fixed hourly loads, responsive loads are modeled with their intertemporal characteristics. The responsive loads linked to hourly market prices can be curtailed or shifted to other operating hours. The study results show that DR could shave the peak load, reduce the system operating cost, reduce fuel consumptions and carbon footprints, and reduce the transmission congestion by reshaping the hourly load profile. Numerical simulations in this paper exhibit the effectiveness of the proposed approach.
