“…This DL use is the same as that in WO mode in no-ESS [6]. Additionally, WO mode simulations are also presented in the wind hydro isolated microgrid of [85], where a simulation of the transition from WO mode to windmode (the mode where both the HTG and WTG are supplying) is also shown. DGs and WTGs are also combined with other renewable power generators, such as in power plant of El Hierro Island in Spain, which combines wind, hydro and diesel power sources.…”

Wind diesel isolated microgrids (WDIMs) combine wind turbine generators (WTGs) with diesel generators (DGs) to supply electricity to remote consumers. WDIMs are low-inertia isolated power systems where large system frequency and voltage variations occur. WDIM dynamic modeling allows short-term simulations to be performed and detailed electrical variable transients to be obtained so that the WDIM power quality and stability can be tested. This paper presents a literature review about WDIM dynamic simulation. The review classifies articles according to factors such as the different WDIM operation modes (diesel only, wind–diesel and wind only) simulated, the types of WTGs used in the WDIM (constant- and variable-speed types), or the use of different short-term energy storage technologies (batteries, ultracapacitors, flywheels) to improve the WDIM power quality, stability and reliability. Papers about the dynamic simulation of related isolated microgrids are also reviewed. Finally, as an example of WDIM dynamic simulation, a WDIM with one WTG, one DG, load and a discrete dump load (DL) is modeled and simulated. The WDIM response to variations of wind speed and load consumption is shown by graphs of the main electrical variables. The simulations show how the DL is used to improve the WDIM stability and reliability.

“…However, in the presence of hydro resources with required water head and flow, if stable power consumption is observed, preference should be given to a hydraulic IPS due to its independence of the fossil fuel. For a more optimal use of hydro resources, it is advisable to consider the possibility of building a hydro-wind IPS [1,2]. The independence from the fossil fuel, lower cost of electricity production compared to diesel and wind-diesel power plants, and good predictability of hydro resources have caused the interest in problematic issues and searching approaches for improving technical characteristics of hydraulic IPSs.…”

Such methods as droop method, curve shifting method and master-slave method were primarily developed for voltage and frequency regulation in isolated power systems with synchronous generators. In modern power systems induction generators, regulated dump loads, energy storage devices with AC/DC and AC/DC/AC power converters, etc. are used in addition to synchronous generators. The investigation of new configurations of power systems is closely tied with further development of control methods for load sharing and regulation of voltage and frequency of the systems. The article reviews simple-to-implement known control methods used for control of isolated power systems with parallel operated synchronous generators and proposes a modification of the master-slave method for control of power systems with parallel operated synchronous and induction generators, static var compensators, dump loads and energy storage devices with interface power converters. The system “Hydroelectric unit with a synchronous generator - dump load - hydroelectric unit with an induction generator - compensating capacitors - transformer – AC local load" is considered and two techniques for regulation of electric frequency and voltage magnitude in the specified system are presented with accordance to the statements of the proposed modified method. The proposed control algorithm of the dump load frequency controller is in agreement with the control algorithm of the speed controller of the master unit. The functions assigned to the electronic PID speed controller of the master unit are to maintain the electric frequency in the system equal to nominal value and regulate the active power sharing. Verification of the proposed control algorithms for isolated electric power systems was carried out. References 23, figures 5, table 1.
