OATAO is an open access repository that collects the work of some Toulouse researchers and makes it freely available over the web where possible. Abstract-In this paper, we investigate a design approach aiming at simultaneously integrating the energy management and the sizing of a small microgrid with storage. We particularly underline the complexity of the resulting optimization problem and how it can be solved using suitable optimization methods in compliance with relevant models of the microgrid. We specifically show the reduction of the computational time allowing the microgrid simulation over long time durations in the optimization process in order to take seasonal variations into account. The developed approach allows performing many optimal designs in order to find the appropriate price context that could favor the installation of storage devices.

“…The sizing study optimized the sizes of the solar panel, batteries and generators, as well as the power dispatch over a period of one year using a forward-looking strategy to minimize annualized capital and fuel costs. The mathematical formulation of this nested component sizing and dispatch optimization is adopted from [23] and only the results are summarized here for brevity.…”

“…While component sizing is often performed based on the expected peak load of the microgrid, it has also been recognized that this approach may be highly conservative and sub-optimal, as many components will be larger than necessary. Power dispatch control strategies can be used to reduce this conservatism, but at the cost of coupling the optimal sizing and dispatch problems [14]- [23]. On the other hand, the regulation problem focuses on controlling the voltage and frequency in the microgrid.…”

Abstract-Increasing energy security and reliability concerns are intensifying the interest in microgrids. In this setting, design optimization is vital to achieve a reliable infrastructure without overbuilding. This paper considers the impact of frequency and voltage regulation on the optimal design of a conceptual, autonomous military microgrid. This microgrid comprises a solar panel and vehicles as power sources, with each vehicle incorporating a battery and generator. The power output and terminal voltage of these inverter-based sources must be regulated. The paper investigates the effects of battery DC voltage variations on a decentralized regulation scheme, and the resulting influence on optimal component sizing. To this end, controllers are first designed based on the typical assumption that the voltage on the DC side of each inverter is constant. The battery internal resistance is then considered and its impact on regulation performance is investigated. The results show that the battery internal resistance can affect the performance of both frequency and voltage regulation, and consequently must be taken into account in component sizing decisions. Thus, the paper identifies an important coupling between regulation and component sizing problems through battery characteristics, and highlights the need for a combined sizing and regulation framework for microgrid design.

Increasing concerns about energy security and reliability are intensifying the military's interest in the microgrid technology. This paper focuses on the frequency and voltage regulation part of a case study that seeks to design a conceptual military microgrid that has to operate completely autonomously. This microgrid comprises a solar panel and vehicles as power sources, where the vehicles contain a battery and generator, and managing their power setpoints is the control problem of interest. The goal is to investigate the validity of assuming the battery as a constant voltage source during the control design. To this end, the control design is first carried out assuming the battery as a constant voltage source. It is then illustrated how critical this assumption can be depending on the battery internal resistance. The results show that the battery internal resistance can affect both frequency and voltage regulation performances, thereby highlighting the coupling between the battery characteristics and control design, and the need for a control design framework that takes this coupling into account.
