随着发展中国家电气化项目的数量和密度增加，很快就会达到这样一个点，即存在足够数量的相互接近的孤岛微电网，以证明它们的互联可以形成一个更大的电力系统。提出了一种可转换的静止补偿器作为一种使能技术，用于互连孤岛微电网和建立一个微电网间的交易电力市场，实现放松管制的系统模型。所提出的设备可以参与电力供应市场的所有三个部分：精确控制微电网之间的能量市场的功率流;通过传输市场的真实的/无功功率补偿来缓解拥塞;以及辅助服务，包括电压调节、一次频率响应、虚拟同步惯性、振荡阻尼、调节备用和ESS充电控制。此外，一个小时前的能源市场的定价策略和能源经纪人系统的电力交易结算方法也提出了。所提出的框架说明了一个案例研究，在巴布亚新几内亚Jiwaka省的4500居民的社区电气化。
As the number and density of electrification projects in developing countries increases, a point will soon be reached when there exists a sufficient number of islanded microgrids in proximity to each other to justify their interconnection to form a larger power system. A convertible static compensator is proposed as an enabling technology for interconnecting islanded microgrids and establishing an inter-microgrid transactive power market implementing the deregulated system model. The proposed device can participate in all three sectors of the electric supply market: precise control of power flows between microgrids for the energy market; alleviation of congestion through real/reactive power compensation for the transmission market; and ancillary services including voltage regulation, primary frequency response, virtual synchronous inertia, oscillation damping, regulation reserve, and ESS charge control. Additionally, a pricing strategy for the hour-ahead energy market and an energy-broker system method for clearing the Power Exchange are also presented. The proposed framework is illustrated with a case study for electrification of a community of 4500 residents in Jiwaka Province of Papua New Guinea.
