Comparative Analysis between the Government Micro-Grid Plan and Computer Simulation Results Based on Real Data: The Practical Case for a South Korean Island

Abstract: Greenhouse gas (GHG) emissions, which are produced through the combustion of fossil fuels, cause climate change. Unfortunately, South Korea is highly dependent on fossil fuels because of its industrial nature. However, many islands in South Korea have the potential to generate a considerable amount of renewable energy, which should be studied. KEPCO (Korea Electricity Power Corporation), which runs micro-grid facilities in Gasado Island in Jindo, South Korea, built micro-grid facilities in Mozambique in 2015. … Show more

“…The atmospheric CO 2 concentration has increased by approximately 40% compared with that at the beginning of the industrial revolution [4]. These issues have led to the determination of alternative energy sources with the potential to reduce pollution and produce a sustainable energy supply [5]. The utilization of renewable energy sources (RESs) has grown exponentially over the last few years.…”

“…The microgrid frequency was then reduced to 59.37 Hz and the diesel generator increased the active power to 145.9 kW via the droop control. The active power output of the BESS was also increased to 236.1 kW, as shown in Equations (12) and (17), enabling the further recovery of the voltage drop. This coordinated control between the BESS and the diesel generator caused the microgrid voltage to rise by acquiring additional primary active power reserve in the microgrid.…”

“…In [16], a constant-voltage constant-frequency (CVCF) control scheme was adopted for BESSs to maintain frequency and voltages at their rated levels and consequently achieve real-time power balance in an isolated microgrid. In [17][18][19][20][21][22][23][24][25][26], the control scheme was practically applied to isolated microgrids in remote islands (including several islands in South Korea) mainly due to simple implementation and low fluctuations in grid frequency and voltages. However, the scheme requires large capacities of battery and inverters to achieve the real-time power balance under the condition on large variations in load demand and RES power outputs.…”

“…The biggest number of researches can be covered under the cost minimization studies [94][95][96][97][98][99][100][101][102][103] using LP or nonlinear programming (NLP) method. Alharbi and Bhattacharya 94 studied the net present value of the storage systems with a stochastic and linear approaches combined.…”
