“…Load-management procedures involve changes to equipment and/or consumption patterns on the customer side. There are many methods of load management which can be followed by an industry or a utility, such as load shedding and restoring, load shifting, power wheeling, installing energy-ecient processes and equipment, energy storage devices, co-generation and non-conventional sources of energy, and reactive power-control [3].…”

“…The fluctuation of the electricity prices may result from the new peak demand. This phenomenon is similar to so-called 'payback effect' [31][32][33][34], which can appear as a form of delayed consumption when the demand is restored after the service interruption.…”

-A thermostatically controlled load (TCL) can be one of the most appropriate resources for demand response (DR) in a smart grid environment. DR capability can be effectively implemented in a TCL with various intelligent control methods. However, because traditional on-off control is still a commonly used method in a TCL, it is useful to develop a method for adding DR capability to the TCL with an existing on-off controller. As a specific realization of supervisory control for implementing DR capability in the TCL, two methods are proposed -a method involving the changing of a set point and a method involving the paralleling of an identified system without delay. The proposed methods are analyzed through the simulations with an electric heater for different power consumption levels in the on-state. Considerable cost benefit can be achieved with the proposed methods when compared with the case without DR. In addition, the observations suggest that a medium power consumption level, instead of the maximum power, in the on-state should be used for consistently obtaining the cost benefit without severe temperature deviation from the specified temperature range for DR.

“…Zhang et al [19] builds a highly accurate aggregated model for a heterogeneous population of AC loads and designs a novel aggregated control strategy for the load population under realistic conditions. To provide a daily control scheduling, the dynamic programming algorithm is presented and optimized for groups of interruptible AC loads [20][21][22].To avoid the transient payback load phenomenon, a group-direct load control (DLC) program of air-conditioning systems is proposed with a least enthalpy estimator-based thermal comfort controller [23]. Goel et al [24] provides a fuzzy logic based DLC scheme for AC loads which can achieve a good tradeoff among peak load shaving, system operating cost reduction and system reliability improvement.…”

With the gradually widely usage of the air conditioning (AC) loads in developing countries, the urban power grid load has swiftly increased over the past decade. Especially in China, the AC load has accounted for over 30% of the maximum load in many cities during summer. This paper proposes a scheme of constructing a virtual peaking unit (VPU) by public buildings' cool storage central AC (CSCAC) systems and non-CSCAC (NCSCAC) systems for the day-ahead power network dispatching (DAPND). Considering the accumulation effect of different meteorological parameters, a short term load forecasting method of public building's central AC (CAC) baseline load is firstly discussed. Then, a second-order equivalent thermal parameters model is established for the public building's CAC load. Moreover, the novel load reduction control strategies for the public building's CSCAC system and the public building's NCSCAC system are respectively presented. Furthermore, based on the multiple-rank control strategy, the model of the DAPND with the participation of a VPU is set up. The VPU is composed of large-scale regulated public building's CAC loads. To demonstrate the effectiveness of the proposed strategy, results of a sample study on a region in Nanjing which involves 22 public buildings' CAC loads are described in this paper. Simulated results show that, by adopting the proposed DAPND scheme, the power network peak load in the region obviously decreases with a small enough deviation between the regulated load value and the dispatching instruction of the VPU. The total electricity-saving amount accounts for 7.78% of total electricity consumption of the VPU before regulation.
