“…In particular, battery energy storage systems (BESSs) have been proposed [19][20][21][22][23][24], different sizes and battery technologies have been discussed and their corresponding suitability demonstrated. BESSs are able to react practically instantaneously, and, based on their flexibility in capacity and location, last longer.…”

Due to the promoted integration of renewable sources, a further growth of strongly transient, distributed generation is expected. Thus, the existing electrical grid may reach its physical limits. To counteract this, and to fully exploit the viable potential of renewables, grid-balancing measures are crucial. In this work, battery storage systems are embedded in a grid simulation to evaluate their potential for grid balancing. The overall setup is based on a real, low-voltage distribution grid topology, real smart meter household load profiles, and real photovoltaics load data. An autonomous optimization routine, driven by a one-way communicated incentive, determines the prospective battery operation mode. Different battery positions and incentives are compared to evaluate their impact. The configurations incorporate a baseline simulation without storage, a single, central battery storage or multiple, distributed battery storages which together have the same power and capacity. The incentives address either market conditions, grid balancing, optimal photovoltaic utilization, load shifting, or self-consumption. Simulations show that grid-balancing incentives result in lowest peak-to-average power ratios, while maintaining negligible voltage changes in comparison to a reference case. Incentives reflecting market conditions for electricity generation, such as real-time pricing, negatively influence the power quality, especially with respect to the peak-to-average power ratio. A central, feed-in-tied storage performs better in terms of minimizing the voltage drop/rise and shows lower distribution losses, while distributed storages attached at nodes with electricity generation by photovoltaics achieve lower peak-to-average power ratios.

“…The former is usually considered to be a serious problem in PV systems due to the severe operational problems for the utility grid caused by variations in solar irradiance (depending on climacteric conditions or on panel placement), power swings in lines, both under and over loading, critical voltage fluctuations and voltage flickers [38]. This is much more relevant in rural facilities with radial distribution systems and with automatic disconnection of the inverter from the grid due to overvoltage beyond the technical established limit (253 V).…”

Impact of Rural Grid-Connected Photovoltaic Generation Systems on Power Quality

et al. 2016

Photovoltaic (PV) generation systems have been increasingly used to generate electricity from renewable sources, attracting a growing interest. Recently, grid connected PV micro-generation facilities in individual homes have increased due to governmental policies as well as greater attention by industry. As low voltage (LV) distribution systems were built to make energy flow in one direction, the power feed-in of PV generation in rural low-voltage grids can influence power quality (PQ) as well as facility operation and reliability. This paper presents results on PQ analysis of a real PV generation facility connected to a rural low-voltage grid. Voltage fluctuations and voltage harmonic contents were observed. Statistical analysis shows a negative impact on PQ produced by this PV facility and also that only a small fraction of the energy available during a sunny day is converted, provoking losses of revenue and forcing the converter to work in an undesirable operating mode. We discuss the disturbances imposed upon the grid and their outcome regarding technical and economic viability of the PV system, as well as possible solutions. A low-voltage grid strengthening has been suggested and implemented. After that a new PQ analysis shows an improvement in the impact upon PQ, making this facility economically viable.

Co-production in distributed generation: renewable energy and creating space for fitting infrastructure within landscapes

This review describes the infrastructural elements of the socio-technical system of power supply based on renewables and the role of landscape concerns in decision-making about emerging 'intelligent grids' . The considerable land areas required for energy infrastructure call for sizable 'distributed generation' close to energy consumption. Securing community acceptance of renewables' infrastructure, perceived impacts on the community, and 'landscape justice' requires two types of co-production: in power supply and in making space available. With co-production, landscape issues are prominent, for some options dominant. However, 'objectification' of landscape, such as the use of 'visibility' as proxy for 'visual impact' , is part of lingering centralised and hierarchical approaches to the deployment of renewables. Institutional tendencies of centralisation and hierarchy, in power supply management as well as in siting, should be replaced by coproduction, as follows from common pool resources theory. Co-production is the key to respecting landscape values, furthering justice, and achieving community acceptance.
