Risk Assessment of Island Microgrid

What are the challenges of Island grids and microgrids?

One challenge of island grids and microgrids is to maintain the balance between production and consumption. Diesel generators are still frequently used for this task. Due to the unavoidable dependence on fuel price and delivery options, and the environmental impact, alternatives are being sought.

What are the strategies for the island microgrid optimization problem?

The following strategies for the island microgrid optimization problem is compared. RMPC-based optimization (RMPCO) strategy: This strategy is proposed in this paper. It is the feedback control law generated from the RMPC control framework, where the forecast uncertainties are considered in a robust optimization way.

What are the risks of microgrid installation?

The RESCO is protected from the following risks during microgrid installation: (i) Execution risk – risk of delays that may arise during the EPC phase of microgrid installation, (ii) Performance risk – risk of less than expected operational performance of the microgrid asset over its useful life, (iii) Technology risk – risk of outdated technology.

What is an islandable microgrid?

An islandable microgrid is a condition in which distributed generators (DG) continue to provide power in a location even without the continued presence of electrical grid power. This handbook focuses on these islandable microgrids. Currently, the majority of the world’s microgrids are in the North America and the Asia and Pacific region (Figure 2).

Why do we need a reserve capacity for Islanded microgrids?

Abstract: Due to the lack of support from the main grid, the intermittency of renewable energy sources (RESs) and the fluctuation of load will derive uncertainties to the operation of islanded microgrids (IMGs). It is crucial to allocate appropriate reserve capacity for the economic and reliable operation of IMGs.
