“…Different scenarios and operation cases, especially worst cases that cannot be tested in the real network, were simulated and the results obtained were mathematically analyzed offline and improved to reach the most appropriate algorithm for solving voltage problems caused by DGs or different operation cases. These insights led to different redesigns and development iterations [18], [23].…”

This paper describes the process of developing and validating controller concepts using real-time simulation capabilities. The process from the proof-of-concept to the prototype and finally to the realization and the advantage of testing in a realtime simulation environment is demonstrated in a test case. The test case is based on an example in the safety critical domain of electric power systems -the coordinated voltage controller of the DG-DemoNet project. The possibilities and advantages of controller-hardware-in-the-loop (C-HIL) concepts compared to offline simulation are discussed.

“…However, the formulation considers only uncertainty in network admittances and has been tested only in a balanced network. In [24], interval method and linear model of the network are used to consider uncertainties in a balanced system. However, this work considers neither distributed generator nor SC.…”

“…Also, the coordinated voltage controller in the distribution network with the penetration of DGs and MG was considered as an important optimization problem formulation. In this context, several optimization techniques with different objective functions such as minimizing the voltage deviation, system losses and reducing the tap movements and switching capacitor banks have been deployed [29][30][31][32][33][34][35][36][37][38][39][40][41]. The voltage control for the islanded MG becomes a challenge due to the low X/R ratio so that the intermittency of renewable based DGs will significantly impact the voltage profile.…”

This paper introduces a novel framework of coordinated voltage and frequency control strategy for islanded Microgrid (MG) operation. The proposed control schemes rely on local measurements as communication-free control approach. Therefore, the distributed controllers of the MG components have been deployed based on their slow, medium and fast dynamic responses to maintain the voltage and frequency in adherence to IEEE Standards 1547 and 929. The various voltage and frequency control responses associated with reactive power management scheme are efficiently utilized based on well-defined states of operation and transient management scheme. In each state, the roles of each device for voltage and frequency regulations are defined with its regulation capability and response time based on its local measurements. Consequently, the fast reactive power compensation and rapid frequency regulation are ensured based on the inverter based devices at challenging operating conditions. As a result, the proposed control strategy improves the voltage and frequency regulation, transient response and MG stability. A comprehensive simulation study has verified the superior performance of the communication-free approach during steady state and in response to severe disturbances.

Therefore, the coordination between the DGs and OLTC is proposed with managing the active and reactive power generation from DGs to achieve an effective voltage regulation. This coordinated voltage control has inquired high band width communication infrastructure resulted in increasing the system complexity [25][26][27].In [28], a new method was proposed to minimize the requirement of communication infrastructure by employing the state estimator. The coordinated voltage control based on Multi-Agent System has been deployed among the OLTC, capacitor banks and DGs. The OLTC was controlled based on a line drop compensation scheme so that few RTUs were installed at selected buses, mainly for the DGs and capacitor banks; also, the voltage profile along the feeder was estimated. The measured and estimated voltages at all buses have been processed to identify the pilot bus to control the OLTC. Consequently, the generation status of the DGs has been accounted in controlling the OLTC to avoid the violation of operating voltage criteria along the feeder. Also, the coordinated voltage controller in the distribution network with the penetration of DGs and MG was considered as an important optimization problem formulation. In this context, several optimization techniques with different objective functions such as minimizing the voltage deviation, system losses and reducing the tap movements and switching capacitor banks have been deployed [29][30][31][32][33][34][35][36][37][38][39][40][41].
