“…We compare the consumptions of curtailed wind power in the following two modes: Mode 1: Coordinating the regulation capacity of energy-intensive loads and curtailed wind power considering the ancillary regulation of coal-fueled units (employing the coordinative model proposed in this paper, see Equation 1- (4) and 12- (18)).…”

“…Only a few have investigated the coordination of energy-intensive loads and wind power. Bao [17] and Xu [18] employed energy-intensive loads to support the frequency control of power system integrated with wind power. Liao [19] proposed a direct control scheme of energy-intensive loads to smooth the wind power fluctuation, but the wind power consumption is not the research emphasis in the mentioned literatures.…”

Large-scale wind power farms in China are suffering from large amounts of curtailed wind power in the conventional dispatching mode. Energy-intensive loads have great potential in providing service regulation to help consume the curtailed wind power. However, constrained by technical limitations, the regulating power of energy-intensive loads cannot fully follow the fluctuating wind power. This would result in insufficient utilization of the regulation capability of energy-intensive loads, which limits the promotion in consumption of curtailed wind power brought by load-source coordination. With this concern, a brand new method for further consuming the curtailed wind power, which involves using coal-fueled units to provide ancillary regulation for the coordination of energy-intensive loads and wind power is presented, and a corresponding bi-level coordinative model is also established. The first level of optimization is intended to maximize the consumption of curtailed wind power with minimum ancillary regulation energy. The second level of optimization is to allocate the ancillary regulating power with minimum regulation cost. Wind power consumption was increased by 3,369.25 MWh and utilization rate of energy-intensive loads was promoted to 100% in the case analysis, which verifies the effectiveness of the proposed method.

“…For large-capacity single DSRs, the intermittent characteristics are particularly obvious, i.e., heavy industry load [19,20], large charging station for electric vehicle [21] and centralized commercial air conditions [18]. For aggregation of DSRs, like a curtailment service providers (CSP) [22], the intermittent characteristics will be less noticeable and may even disappear.…”

Recently, demand-side resources (DSRs) have proceeded to participate in frequency control of the power systems. Compared with traditional generation-side resources, DSRs have unique intermittent characteristics. Taking aggregation of air conditions as an example, they must take a break after providing power support for a period of time considering the user comfort. This behavior, known as the intermittent characteristic, obviously affects the stability of the power systems. Therefore, this paper designs a corresponding controller for DSRs based on the intermittent control method. The designed controller is incorporated into the traditional load frequency control (LFC) system. The time delay is also considered. A rigorous stability proof and the robust H ∞ performance analysis is presented for the new LFC system. Then, the sufficient robust frequency stabilization result is presented in terms of linear matrix inequalities (LMIs). Finally, a two-area power system is provided to illustrate the obtained results. The results show that the designed intermittent controller can mitigate the impact of intermittent characteristics of DSRs.

“…Minute-to-minute regulation of electrolysis aluminum loads is achieved in [17] by manually controlling the ratio of the voltage-regulating transformer. A frequency feedback control framework is proposed to allow aluminum smelter loads (ASLs) for system frequency control in an isolated power system by controlling the generator's excitation voltage [18,19] or the saturation reactor of the ASL [20]. Based on this architecture, experimental verification of ASLs for frequency regulation is reported in [21,22] based on the real-world isolated power system.…”
