“…But, they do not consider the fact that end user's reactive power sources change whenever they are on or off. Aquino-Lugo et al [2] explained little about the distribution systems, they do not explain about the process of acquiring the sensitivity matrix and reactive support grouping in the distribution systems. Also, distributed energy resources of end-users have important role in modern systems, it is better to consider other resources such as distributed generation (DG) and storage with reactive power resources.…”

As a part of prosumer concept, reactive power supply using the end user equipment is evolving. Reactive power injection using end user appliances is used for voltage profile correction, reduction in losses and improvement in power factor. In a radial distribution network, when there are reactive power supplying devices available at different locations, selection of reactive power source will have greater impact on the network. So, the main focus of this paper is to find the optimal location of the bus for reactive power injection based on availability. Since the objective is to reduce losses in the network optimal location is found using the sensitivity matrix for power loss with changes in reactive power injection. Also, the system energy is energy is computed. In order to demonstrate the proposed algorithm a case study is done for IEEE 33 bus radial distribution system in MATLAB programming. Results obtained show that the reduction in losses is about 20%. This proves that end user reactive power equipment is helpful in improving the network profile.Keywords Prosumer · Reactive power support · End user equipment · Voltage profile Charan Teja S

When energy prices change during the day, users will schedule their appliances with the aim of minimizing their bill. If the variable price component depends on the peak demand during each given hour, users will distribute their consumption more evenly during the day, resulting in lower peak consumption. The process can be automated by means of an Energy Management System that chooses the best schedule that satisfies the user's delay tolerance threshold. In turn, delay tolerance thresholds may slowly vary over time. In fact, users may be willing to change their threshold to match the threshold of their social group, especially if there is evidence that friends with a more flexible approach have paid a lower bill. We show that social interaction can increase the flexibility of users and lower the peak power, resulting in a more smooth usage of energy throughout the day.

“…A control system based on multi-agent technique that coordinates different discrete and continuous control devices during the post-disturbance period to prevent voltage collapse of the whole system is presented in [12]. Reference [13] describes the coordination of reactive power supply devices based on optimization of the system voltages.…”

The presence of distributed generators (DGs) with high penetration poses new challenges in the management and operation of electrical grids. Due to the local character of DGs, they could in principle be used in emergency situations to prevent a voltage instability event of the grid. In this paper, a certain method is proposed to coordinate the operation of virtual power plant (VPP) and conventional voltage regulation device to improve the static voltage stability of distribution network with the multi-agent framework. The concept and the general framework of this coordinated control system is introduced, and the voltage instable nodes are determined based on the voltage instability indicator. The voltage coordinated control model of the distribution system is established according to the multi-agent consistency control theory and the coordinated controllers for agents are designed by solving a problem with bilinear matrix inequality constraints. The suggested method is implemented on an IEEE 33 nodes test system and the simulation results show its efficiency and validity.
