“…Therefore, we consider it unlikely that a high number of new large scale storage facilities will be built in near future. Small scale storage solutions, in contrast, are on the verge of becoming profitable (see Colmenar-Santos et al, 2012) and this profitability increases with increasing electricity prices, as shown in Mishra et al (2012). In addition, their installation is a private decision of households, which is in line with our assumptions about the consumers.…”

The diffusion of renewable electricity generating technologies is widely considered as crucial for establishing a sustainable energy system in the future. However, the required transition is unlikely to be achieved by market forces alone. For this reason, many countries implement various policy instruments to support this process, also by re-distributing related costs among all electricity consumers. This paper presents a novel history-friendly agent-based study aiming to explore the efficiency of different mixes of policy instruments by means of a Differential Evolution algorithm. Special emphasis of the model is devoted to the possibility of small scale renewable electricity generation, but also to the storage of this electricity using small scale facilities being actively developed over the last decade. Both combined pose an important instrument for electricity consumers to achieve partial or full autarky from the electricity grid, particularly after accounting for decreasing costs and increasing efficiency of both due to continuous innovation. Among other things, we find that the historical policy mix of Germany introduced too strong and inflexible demand-side instruments (like feed-in tariff) too early, thereby creating strong path-dependency for future policy makers and reducing their ability to react to technological but also economic shocks without further increases of the budget.

“…This is shown in Figure 4, where total cost decreases with the initial increase in autogeneration content. There are markets where this trigger is already a reality for solar PV autogeneration, for example in Spain [15,47]. In this case, the modularity of photovoltaic (PV) power implies that small penetrations, with less installed power are not so much more expensive per kW, compared to other generation sources.…”

This paper presents a novel methodology for assessing islanding microgrids from the economical and functional perspective, for various stakeholders. The paper proposes the triggers for competitive deployment of microgeneration, storage, microgrid islanding, the market conditions that apply, and discusses the future tendencies and the policy recommendations to foster microgrid benefits. The validation of the proposed scheme is based on real market cases, where the triggers for autogeneration and islanding microgrids are present. Additionally, the new concept of grid independence cycle is presented and analyzed. The policy implications of a situation where grid consumption reduction leads to higher energy prices are presented and discussed. The paper concludes with a summary of prioritized technical and regulatory recommendations, proposed as a result of the assessment.

“…Citizens who have installed PV modules on roofs are an example of distributed power generation at residential level, but they are also carriers of important benefits for the environment and the rest of the electrical system. If properly managed, prosumers may contribute to improving the system stability and reduce overall losses [8,9]. On the other hand, the increasing electrification will put the reliability and stability of distribution grids under pressure.…”

The paper presents a review of the recent developments of photovoltaics integrated with battery storage systems (PV-BESs) and related to feed-in tariff policies. The integrated photovoltaic battery systems are separately discussed in the regulatory context of Germany, Italy, Spain, United Kingdom, Australia, and Greece; the attention of this paper is focused on those integrated systems subject to incentivisation policies such as feed-in tariff. Most of the contributions reported in this paper consider already existing incentive schemes; the remaining part of the contributions proposes interesting and novel feed-in tariff schemes. All the contributions provide an important resource for carrying out further research on a new era of incentive policies in order to promote storage technologies and integrated photovoltaic battery systems in smart grids and smart cities. Recent incentive policies adopted in Germany, Italy, Spain, and Australia are also discussed.
