摘要:

以新能源为主的新型电力系统的功率平衡面临着重要的技术挑战,以灵活负荷参与电力系统调节是提升新型电力系统有功平衡能力的重要途径。针对电热负荷季节性、时段性特征明显,新能源“极寒极热无风”“晚峰无光”,热电负荷在新型电力系统中呈现反调峰的趋势。针对这一问题,全面分析了电热负荷时空特性和用能特性,深入挖掘其调节潜力,着重分析了电热可控负荷的控制场景,并系统地给出了电热负荷的柔性调度策略,完成电热负荷的柔性控制调节,实现全时间尺度的网荷协同优化和灵活调度,从而验证了该电网电热负荷实时参与调度的可行性。

Abstract:

The power balance of the new power system mainly based on new energy is facing an important technical challenge, and the participation of flexible load in power system regulation is an important way to enhance the active balance capability of the new power system. In view of the obvious seasonal and temporal characteristics of the electric and thermal loads, the new energy sources are “extremely cold and hot without wind” and “late peak without light”, and the thermoelectric loads in the new power system show the trend of anti-peak regulation. To address this problem, this paper analyzed the spatial and temporal characteristics and energy-use characteristics of electric and thermal loads, explored their regulation potential, focused on the control scenarios of electric and thermal controllable loads, and systematically gave a flexible scheduling strategy for electric and thermal loads to complete the flexible control and regulation of electric and thermal loads. The results realize the network-load cooperative optimization and flexible scheduling on the whole time scale, and thus verify the feasibility of the real-time participation of telectric and thermal loads in the scheduling of the grid.
