“…In this section, the proposed P2P reactive power trading algorithm is applied on the modified IEEE 37-bus test system [43] shown in Figure 4 in order to investigate its performance in managing reactive power injections in a multi-agent structure. The simulation has been conducted with MATLAB in a machine with 6GB RAM and Core i5-4200U 1.6 GHz processor.…”

In recent years, distributed structures have been developed in distribution networks as a result of privatization as well as integration of independently operated distributed energy resources (DERs) into the grid. In this context, effective management techniques seem to be necessary to enable decentralized operation of systems that have been consisted of multiple agents. Accordingly, novel management schemes should be applied in such systems to enable the distributed reactive power management, which would finally improve voltage profile in the network. As a result, this paper develops a distributed algorithm for reactive power management in multi‐agent distribution systems with the aim of improving the voltage profile of the grid. Correspondingly, in the proposed framework, several cost functions are developed to model the effects of reactive power management on the system from the distribution system operator (DSO) as well as agents’ perspectives. Consequently, the proposed reactive power management algorithm would result in voltage profile improvement, while each agent of the system merely strives to maximize its own profits. Accordingly, the proposed scheme ensures the privacy of independent agents. Finally, the proposed scheme is applied on the modified IEEE‐37‐bus test system to investigate its effectiveness on Peer‐to‐Peer (P2P) reactive power management in multi‐agent systems.

“…Respectively, while the scarcity of the ramping capability in power systems would increase the operational costs; the increase in the ramping capability would facilitate the integration of RESs without deteriorating the reliability criteria. Traditionally, power system operators rely on bulk generation units connected to transmission networks to provide the required flexibility service; while the decreasing operational costs of RESs, as well as high investment costs and construction time of conventional resources, would decrease the ramping capacity provided by bulk power units [1], [3], [4]. That is why system operators should focus on activating the flexibility service from active distribution systems.…”

The increasing trend of integrating Renewable Energy Sources (RESs) into power systems could cause operational challenges in the system from flexibility and reliability perspectives. Respectively, utilities would be relied on local flexible resources to address the flexibility requirements in power systems. In this respect, local resources in distribution systems could participate in ancillary markets along with the wholesale energy markets to address the flexibility capacity shortage in the system. Consequently, this paper aims to provide a framework to optimize the scheduling of resources in distribution networks while participating in energy, regulation, and ramp markets. Correspondingly, this approach would maximize the profits of the local resources in distribution systems whereas providing Flexible Ramp Product (FRP) and regulation reserve for the system operators. Respectively, an optimized bidding strategy is developed to maximize the profits of the local resources, while modeling the operational constraints of the distribution grids and power losses to improve the accuracy of the proposed scheme. Furthermore, the chance constrained concept is taken into account in the proposed scheme to model the uncertainty of RESs. Finally, the model is applied on the IEEE-37-bus-testsystem and the sensitivity analysis is employed to investigate its effectiveness in the management of the system.

“…International stakeholders try to improve the environmental conditions around the world with the help of agreements and policies like the Paris Climate Agreement. In the power sector, to meet the increase in energy demand, the use of renewable systems with grid-connected inverters (GCIs) increases with every passing year [1][2][3][4][5][6][7][8]. However, the energy demand and supply imbalance and the use of GCIs cause harmonic injection and frequency fluctuations in the grid [9][10][11][12][13][14][15].…”

The extensive use of renewable energy systems with grid-connected inverters (GCIs) causes harmonic injection. Similarly, the imbalance in energy demand and supply causes frequency fluctuations. As a result of the increased harmonics and frequency fluctuations, the accuracy of power measurement using conventional methods continues to decline. Precision in power measurement is an essential factor for the billing and management of power supply and demand. Moreover, it is challenging to build a supply plan for the power demand and to manage the billing for the power consumption. To solve these problems, this paper proposes a novel method based on Lock-in Amplifier (LIA) and Lock-in Amplifier Frequency-Locked Loop (LIA-FLL) to measure the power with high precision and accuracy. The proposed method first tracks the variations in the input signal frequency using LIA-FLL and generates the updated reference signals for LIA. After that, the LIA is used to extract the accurate amplitude of each frequency component. The proposed method results in accurate and precise measurement, even with harmonics and frequency fluctuations. The validity of the proposed method is verified by comparing the power measurement results with the classical method, FFT, and ZERA COM3003 (a commercially available power measurement reference instrument).
