As a result of my research, I can conclude that a solar, hydro, and biogas minigrid would be feasible for 90% electrification of Grand-Goâve, and the greatest obstacle to its implementation is the price. With proper policy and pricing, this minigrid will be a viable option to power the city of Grand-Goâve, and the relatively similar geography throughout Haiti suggests that similar systems would work in other communities. I came to this conclusion through a meta-analysis of the different energy potentials with the help of the HOMER program. Minigrids have been effective in similar environments, so it is likely that one would work in Haiti. While the full capacity minigrid is very expensive (around $12.9 million), a smaller, more limited minigrid would be less costly and still benefit the city of Grand-Goâve.
For energy generators: At present the only way companies that generate their own power can monetise excess capacity is to sell it back to the grid on a Feed-in Tariff (FiT) basis. Piclo will provide these companies with a dynamic online market where they are able to control exactly who they sell power to and at what price. The platform should enable smaller generators to get better prices for power than they would currently be able to achieve through FiT. Piclo’s analytics tools will provide generators with information on the current energy market and demand levels at different price points. Producers will also be able to market the story behind their project and have the ability to offer different prices to different buyers – for example offering lower pricing to local businesses.
The cost of producing renewable energy from the environment has undergone a significant decrease of the past 15-20 years as a result of drastic enhancements in not only the economies of scale, but also the technology that is related to production. Renewable energy’s future prospects are noted to be even more promising in light of the continually falling costs involved in producing this energy as well as the growing awareness of the energy and environmental security benefits that these technologies provide.
With the potential rise of grid-scale energy storage there is an issue regarding regulation and policy as is being experienced by companies who are currently implementing this technology. The integration of any new technology faces many barriers and so is it with the deployment of grid-scale energy storage like any other technology. The issue regarding regulatory and policy is that a framework is not in place for the integration of energy storage on the grid.
Summary: At present, most distributed renewable energy systems produce direct current (DC) electricity which is then inverted to alternating current (AC) and fed into the electric grid. Simultaneously, many modern building loads and storage systems use rectifiers to convert AC grid electricity to DC for use at the load or battery. Onsite use of renewable energy production therefore requires two energy conversions: DC/AC at the point of generation and AC/DC at the load. The Bosch DC Building Scale Microgrid Platform (DCBMP) offers significant benefits relative to conventional AC grid systems by distributing as much solar power as possible to DC loads/storage, and then inverting only the excess power to AC for AC loads and export to the grid. The DCBMP maximizes the utilization of solar energy on-site, smooths the volatility of the PV output, increases the load and storage efficiencies and minimizes dependence on grid-based electricity. The proposal incorporates long-life (20-25 years), commercially ready technology, increasing energy efficiency and improving energy security. These features are provided at a low up-front investment when compared to conventional AC-based systems, enabling a levelized cost of electricity (LCOE) less than $0.14/kWh by 2020 for behind-the-meter PV and storage systems and a lower total cost of ownership for the DC loads and DC resources as compared to other approaches, while providing export power to the utility grid through smart inverter

Technological and manufacturing progress along with climate change concerns are transforming the electric power system with the integration of an increasing number of renewable sources that are difficult to plan and control due to its volatility and lack of active dispatchable control. This is challenging the reliability, efficiency and security of the grid. However, they offer a potentially synergistic development as these Distributed Energy Resources (DERS) can provide the requisite for demand response and reserves for economically sustainable massive renewable energy integration. In spite of that, today’s centralized power markets do not allow for the procurement of reserve services and the accommodation of demand response. In this

If the power quality is poor, it will have drastic effect on the appliances associated with the power distribution network. A micro grid is a local grid that has the ability to operate by itself even when it gets disconnected from the main grid. It provides backup in case of emergencies that render the main grid nonfunctional. This paper provides a detailed study of the changes in power quality for a grid connected micro grid in the various scenarios. MATLAB/Simulink is used to integrate the power sources with the loads. The variable nature of power with distributed generators is examined.
With increased additions of renewable sources in our existing infrastructure, major challenges are arising, as their supply is generally unstable and unpredictable. Too often, integrated renewable sources are curtailed and the energy is wasted for the safety of our existing electrical grid [1-6]. A logical solution would be to include large-scale energy storage systems, which would reduce the curtailment and increase the utilization of these clean sources, such as wind turbines and photovoltaics. A large-scale energy storage system would allow the renewable sources to store excess power during periods of low demand, and provide the stored energy during periods of peak electricity demand. Therefore, allowing renewable sources to provide
Present grid networks are oriented for conventional power generation but are not capable of handling the varied conditions and losses in transmission and inconveniences of power
A more cost-effective approach of electrifying an off-grid community is to use a stand-alone microgrid power generation system that utilizes the available renewable energy resources (RERs).
Problem formulation: To achieve consumer satisfaction in power supply and harness renewable energy, microgrids design and control are essential issues for reliable operation. As the characteristics of the distribution network and high volume power electronics penetration into the network are significantly different from the conventional power system, several issues are raised. Some of the issues, which are a promised field for future research, are described shortly below:
