“…In Sri Lanka, it is expected to increase the share of non-conventional renewables, such as SPV and wind 34 energy, up to 20% by the end of 2020. Recent studies highlight that distributed generation using solar PV (SPV) and 35 wind energy is promising to foster the renewable energy penetration in the market [3], [4]. 36 Energy systems fully driven using renewable energy sources is a dream that wider community of researchers try to 37 make a reality [5]- [9].…”

9A paradigm change in energy system design tools, energy market, and energy policy is required to attain the target 10 levels in renewable energy integration and in minimizing pollutant emissions in power generation. Integrating non-11 dispatchable renewable energy sources such as solar and wind energy is vital in this context. Distributed generation 12 has been identified as a promising method to integrate Solar PV (SPV) and wind energy into grid in recent literature. 13Distributed generation using grid-tied electrical hubs, which consist of Internal Combustion Generator (ICG), non-14 dispatchable energy sources (i.e., wind turbines and SPV panels) and energy storage for providing the electricity 15 demand in Sri Lanka is considered in this study. A novel dispatch strategy is introduced to address the limitations in 16 the existing methods in optimizing grid-integrated electrical hubs considering real time pricing of the electricity grid 17 and curtailments in grid integration. Multi-objective optimization is conducted for the system design considering 18 grid integration level and Levelized Energy Cost (LEC) as objective functions to evaluate the potential of electrical 19 hubs to integrate SPV and wind energy. The sensitivity of grid curtailments, energy market, price of wind turbines 20 and SPV panels on Pareto front is evaluated subsequently. Results from the Pareto analysis demonstrate the potential 21 of electrical hubs to cover more than 60% of the annual electricity demand from SPV and wind energy considering 22 stringent grid curtailments. Such a share from SPV and wind energy is quite significant when compared to direct 23 grid integration of non-dispatchable renewable energy technologies. 24

“…A large scale analysis of the integration of the renewable energy sources in the Greek power sector was also performed by Voumvoulakis et al [23]. The analysis concluded that the Greek electricity sector in order to achieve the EU20 goals should be radically transformed; The capacity expansion of the Greek interconnected electric system in the pursuit of the EU20 goals has also been studied applying LEAP (Long range Energy Alternatives Planning Systems), which enables the presentation of the results from the different proposed strategies, rather than leading to the optimum alternative Roinioti et al [24].…”

Renewable energy forms have been widely used in the past decades highlighting a "green" shift in electricity production. An actual reason behind this turn to renewable energy production is EU directives set the Union's target for energy production from renewable sources, greenhouse gas emissions and increase in energy efficiency. All member countries are obligated to apply harmonized legislation and practices and restructure their energy production networks in order to meet EU targets. Towards the fulfillment of 20-20-20 EU targets, in Greece a specific strategy which promotes the construction of large scale Renewable Energy Source plants is been promoted. In this paper, we present an optimal design of the Greek renewable energy production network applying a 0-1 weighted multiperiod Goal Programming model, considering social, ecological and economic criteria. In the absence of a panel of experts Data Envelopment Analysis (DEA) approach is used in order to filter the best out of the possible network structures, seeking for the maximum technical efficiency. Super-Efficiency DEA model is also used in order to reduce the solutions and find the best out of all the possible. The results showed that in order to achieve maximum efficiency, the social and environmental criteria must be weighted more than the economic one.

“…Minimum and maximum allowable bounds of the additional candidate capacity are imposed by constraint (20), subject to the decision whether a unit is to be constructed or not, and considering the construction lead time of each unit. Constraint (21) ensures that each candidate unit is to be constructed at most once during the whole planning horizon.…”

“…Voumvoulakis et al [20] examined the impact that large scale penetration of RES is going to have in order for the GPS to achieve the 2020 RES targets. For that reason, three scenarios were developed with the use of WASP IV software package, characterized by different type and capacity of interconnections, as well as different pumped storage capacities.…”
