“…From panel (e) of Figs 11 and 12, it is seen that frequency control performance of the proposed method is superior to the method described in Ref. 20. From panel (f) of Figs 11 and 12, it is observed that the charging/discharging power required for the proposed method is smaller than in the method described in Ref.…”

“…The most common measure for frequency regulation is the smoothing of fluctuating PV power by using an ESS. Recently, a load frequency control method [20] is introduced for a PV system connected to an isolated power system. The proposed method is compared with this method and the results are given in Figs 11 and 12.…”

“…The proposed method is compared with the MPPT‐based control [19] and the frequency control method given in Ref. 20 through simulation and is found effective in achieving the following key features: frequency regulation by the PV generator as it controls the PV power according to the load variation; supplying the possible maximum amount of PV power to the isolated utility without reducing the reliability of the utility; and reduction of the capacity of the ESS.…”

In this paper, a control method based on a load power estimator and an energy storage system is proposed for isolated power utility-connected photovoltaic-diesel hybrid system to provide frequency control. Here, photovoltaic power is controlled according to the load variation to minimize the frequency deviations. Load power is estimated by a minimal-order observer. Then, a load variation index is calculated. A base photovoltaic power is produced from the available maximum photovoltaic power using a low-pass filter and is added with the load variation index to generate the command photovoltaic power. Simulation results show that the proposed method is capable of providing frequency control and also delivers the photovoltaic power near the maximum level using an energy storage system. 

The microgrid (MG), as an operational paradigm for the exploitation of distributed energy resources (DER), has been thoroughly studied the past few years. However, applications are largely limited to test sites and demo installations, lacking the business argument in favor of the wider deployment of the MG concept. Planned communities (PC), a residential development concept aiming to channel the population growth away from the overcrowded and polluted city centers, can serve as a business model for the application of the MG control architectures and philosophies. This paper intends to link the core characteristics of the PC to existing MG sites and installations, providing evidence of their suitability for MG development.

In this paper, the frequency of a microgrid, that contains a PV generation and a battery energy storage, is controlled. The paper presents a new approach for Load Frequency Control (LFC) in a microgrid considering the low voltage microgrid as an artificial multi-area network and providing a new strategy which can significantly improve the frequency regulation of the microgrid. A Virtual Area Control Error (VACE) is introduced which utilizes a virtual tie-line and includes the State of Charge (SOC) of the battery to take into consideration the realistic characteristics of the device. The system is simulated using PSCAD. The results show a good improvement in frequency regulation.
