This paper evaluates the feasibility of using a hybrid system consisting of wind and tidal turbines connected to a microgrid for power supply to coastal communities that are isolated from a main supply grid. The case study is Stewart Island, where the cost of electricity, provided by a central diesel power station, is higher than the grid network in New Zealand. Local residents believe that reducing the consumption of diesel and having a renewable source of electricity generation are two of the island’s highest priorities. Merging a tidal energy source (predictable) with wind (unpredictable) and diesel (back-up), through a microgrid, may be a way to increase reliability and decrease the cost of generation. Several off-grid configurations are simulated using HOMER and WRPLOT software. Using two wind and four tidal turbines, plus one diesel generator for back-up, is the best design in terms of lower greenhouse gas emissions, higher renewable fraction, and reduced net present cost.

“…From the literature review, only a few researches focused on the multi-energy system consisting of renewable sources, P2G and SOFC/GT. Although this concept has been introduced in some studies, these works mainly focus on either schematic planning [12][21] or operation [14][20] [22] and lack enough depth on thermal adaptability and safety function. However, when the thermodynamic complexity of MES system increases with its structure, the capacity planning and operational function of system become firmly bonded in thermal, economical and manufactural perspectives.…”

“…Considering the limitations of single-objective optimization, other scholars use multi-objective optimization to explore this problem [15][16][17]. (2) The different factors that are considered as main features of microgrid operation models (references [18][19][20]) have investigated the optimal operation of microgrids with consideration of distributed renewable energy. In References [21,22], the optimal operation of microgrids is modeled and solved under the background of smart grids.…”

More and more attention has been paid to the development of renewable energy in the world. Microgrids with flexible regulation abilities provide an effective way to solve the problem of renewable energy connected to power grids. In this article, an optimization strategy of a microgrid participating in day-ahead market operations considering demand responses is proposed, where the uncertainties of distributed renewable energy generation, electrical load, and day-ahead market prices are taken into account. The results show that, when the microgrid implements the demand response, the operation cost of the microgrid decreases by 4.17%. Meanwhile, the demand response program can transfer the peak load of the high-price period to the low-price period, which reduces the peak valley difference of the load and stabilizes the load curve. Finally, a sensitivity analysis of three factors is carried out, finding that, with the increase of the demand response adjustable ratio or the maximum capacity of the electrical storage devices, the operation cost of the microgrid decreases, while, with the increase of the demand response cost, the operation cost of the microgrid increases and, finally, tends to the cost without the demand response. The sensitivity analysis reveals that the demand response cost has a reasonable pricing range to maximize the value of the demand response.
