“…According to the interviewed DSOs, these options are however not (yet) economically and/or technically viable. On the other hand, some academic papers suggest that the regulatory framework is sometimes preventing the implementation of this type of projects [10]. Several DSOs also mentioned regulatory restrictions that hamper innovative solutions.…”

The German experience with integrating photovoltaic systems into the low-voltage grids

a b s t r a c tThe integration of rooftop photovoltaic systems in the low-voltage distribution grids has become a major international trend, helped by the sinking prices for photovoltaics. One of the key questions revolves around the technical challenges brought about by the grid integration of these decentralized systems. This paper therefore analyzes the substantial practical experiences of ten representative German distribution system operators, who play a leading role in this field. Our findings show that grid expansion measures are primarily undertaken to ensure compliance with the permissible limits for voltage and current. Grid optimization measures represent the most economical initial step and include, for instance, changes in grid structure and wide-area control. Once their potential is maximized, classic grid expansion measures such as laying parallel cables are implemented. In individual cases, the low-voltage grid is reinforced by so-called intelligent operating equipment such as voltage regulators or voltage-regulated local distribution transformers. Moreover, improved grid planning measures lead to a better use of the available low-voltage grid capacity. The practical solutions successfully implemented by German distribution system operators should also prove relevant for other countries that are currently planning the deployment of decentralized renewable energies.

“…This is true even in substations and residences distributed over a regional area. This is a serious safety issue for the control of electric power grids because it is not possible to accurately measure PV power generation under different weather conditions . Therefore, information on regionally integrated PV power generation for a regional area in real time and/or on a quasi‐real time scale has been required for distribution system operators (DSO) and transmission system operators (TSO) in power grids.…”

A large number of photovoltaic (PV) power systems have been adopted in Japan after a feed‐in tariff was introduced in 2012. However, PV power generation data from residential rooftop and/or ground‐mounted PV systems, and larger MW‐size PV plants have not been measured accurately in real‐time. This is because PV power monitoring instruments (eg, smart meters) have not collected a sufficient amount of power generation data. In order to realize adequate safety control of electric power systems under high PV‐penetration conditions, it is important to fully understand the temporal and spatial variations associated with PV power generation. In this study, we estimated the PV power generation for a regional area (ie, prefecture or municipality) in terms of PV power installation capacity and satellite‐estimated solar irradiance using a Japanese geostationary satellite, Himawari‐8. The satellite‐derived regionally integrated PV power estimations were validated with reference data provided by electric power companies. The validation results showed that these estimations were comparable to the reference data, provided by the Kyushu Electric Power Company Inc. (Kyushu) and the Tokyo Electric Power Company Inc. (TEPCO). However, the results also identified slight overestimations of PV power in the spring and summer seasons. An advantage of the proposed method is that it does not require land‐based monitoring instruments, which can lead to increased operational cost savings for PV power systems. Furthermore, in consideration of future PV power penetration scenarios, it is suggested that PV power in excess of regional power demands could be generated under the same weather conditions.

Silicon, an earth‐abundant material with mature technology, low‐cost manufacturing, and high stability, holds promise to enable the sustainable exploitation of solar energy resources currently under utilized at the world‐scale. Apart from traditional interest in the photovoltaic industry, recent years have seen increasingly large activity in the study of Si‐based photo‐electro‐chemical (PEC) cells for water splitting and CO2 reduction. This research established an exciting area with the potential to address the present environmental crisis originating from unregulated CO2 emission levels. In this review, the recent work on Si‐based PEC devices for large scale production of hydrogen via water splitting, and carbon‐negative technologies for the solar‐driven reduction of CO2 into chemical fuels of industrial interest are summarized. Bias‐assisted and bias‐free PEC architectures are discussed, highlighting the motivations, challenges, functional mechanisms, and commenting on the perspectives related to this field of research both as a science and engineering.
