“…biomass generator units and gas turbines (GTs)) that are connected to the grids without power electronic interfaces [23]. However, the DERs of the second type, i.e., inverter based-DERs (e.g., fuel cells (FCs), micro turbines (MTs) and photovoltaic (PV) units) are integrated into the grid via power electronic converters [24,25]. Figure 1 shows a schematic structure of a DER connected to the grid via an inverter.…”

In traditional power systems, besides the conventional power plants that provide the necessary reactive power in transmission system, the shunt capacitors along with the tap changers of transformers are also employed in distribution networks. In future years, because of the high number of distributed resources integrated into the distribution networks, it will be essential to schedule complete active-reactive power at distribution level. In this research work, an economic framework based on the active-reactive power bids has been developed for complete active-reactive power dispatch scheduling of smart distribution networks. The economical complete active-reactive power scheduling approach suggested in this study motivates distributed energy resources (DERs) to cooperate in both active power markets and the Volt/Var control scheme. To this end, using DER's reactive power capability, a generic framework of reactive power offers for DERs is extracted. A 22-bus distribution test system is implemented to verify the impressiveness of the suggested active-reactive power scheduling approach.

“…Sousa et al [28] have proposed a new multi-objective methodology to manage the optimally-coupled active and reactive power scheduling in a smart distribution system in the presence of the DGs, electric vehicles, and capacitor banks. Samimi et al [29] have presented a new economical/environmental operational scheduling method based on decoupled day-ahead active and reactive power markets at the distribution level. In the context of the smart grid, four power-demand scheduling scenarios are presented and analyzed in [30] to reduce the peak demand in a smart grid environment.…”

Abstract:One of the most significant control schemes in optimal operation of distribution networks is Volt/Var control (VVC). Owing to the radial structure of distribution systems and distribution lines with a small X/R ratio, the active power scheduling affects the VVC issue. A Distribution System Operator (DSO) procures its active and reactive power requirements from Distributed Generations (DGs) along with the wholesale electricity market. This paper proposes a new operational scheduling method based on a joint day-ahead active/reactive power market at the distribution level. To this end, based on the capability curve, a generic reactive power cost model for DGs is developed. The joint active/reactive power dispatch model presented in this paper motivates DGs to actively participate not only in the energy markets, but also in the VVC scheme through a competitive market. The proposed method which will be performed in an offline manner aims to optimally determine (i) the scheduled active and reactive power values of generation units; (ii) reactive power values of switched capacitor banks; and (iii) tap positions of transformers for the next day. The joint active/reactive power dispatch model for daily VVC is modeled in GAMS and solved with the DICOPT solver. Finally, the plausibility of the proposed scheduling framework is examined on a typical 22-bus distribution test network over a 24-h period.

Featured Application: The incentive method with flexible contribution functions can be applied to demand response by the reactive power market and distribution company, which has the possibility to reduce the additional installation of distribution control equipment and battery capacity. It also leads to the reduction of total electricity purchase cost of consumers, and the power system can achieve high mixing of renewable energy in the grid with the reactive power incentive demand response and the IoT development. Furthermore, reliability assessment of cooperative control with the participation rate will give an important contribution to the robust design of the system. Abstract: In order to solve urgent energy and environmental problems, it is essential to carry out high installation of distributed generation using renewable energy sources (RESs) and environmentally-friendly storage technologies. However, a high penetration of RESs usually leads to a conventional power system unreliability, instability and low power quality. Therefore, this paper proposes a reactive power control method based on the demand response (DR) program to achieve a safe, reliable and stable power system. This program does not enforce a change in the active power usage of the customer, but provides a reactive power incentive to customers who participate in the cooperative control of the distribution company (DisCo). Customers can achieve a reduction in their total energy purchase by gaining a reactive power incentive, whilst the DisCo can achieve a reduction of its total procurement of equipment and distribution losses. An optimal control schedule is calculated using the particle swarm optimization (PSO) method, and also in order to avoid over-control, a modified scheduling method that is a dual scheduling method has been adopted in this paper. The effectiveness of the proposed method was verified by numerical simulation. Then, simulation results have been analyzed by case studies.
