“…This study is aimed at going beyond these averages by proposing a new metric for quantifying the synergies between solar PV and wind power potential for hybrid systems on diurnal and seasonal scales, and demonstrating its implications for the West African context. Solar/ wind power mixes have received substantial attention recently [38][39][40][41][42][43][44][45][46][47][48][49], but assessments for WA, such as [50], are rare. This paper is organised as follows.…”

West African countries' energy and climate policies show a pronounced focus on decarbonising power supply through renewable electricity (RE) generation. In particular, most West African states explicitly focus on hybrid mixes of variable renewable power sources-solar, wind and hydropower-in their targets for the electricity sector. Hydropower, the main current RE resource in West Africa, is strongly sensitive to monsoon rainfall variability, which has led to power crises in the past. Therefore, solar and wind power could play a stronger role in the future as countries move to power systems with high shares of RE. Considering the policy focus on diversified RE portfolios, there is a strong need to provide climate services for assessing how these resources could function together in a power mix. In this study, climate data from the state-of-the-art ERA5 reanalysis is used to assess the synergies of solar photovoltaic (PV) and wind power potential in West Africa at hourly resolution. A new metric, the stability coefficientC stab , is developed to quantify the synergies of solar PV and wind power for achieving a balanced power output and limiting storage needs. Using this metric, it is demonstrated that there is potential for exploiting hybrid solar/wind power in a larger area of West Africa, covering more important centers of population and closer to existing grid structures, than would be suggested by average maps of solar and wind resource availability or capacity factor for the region. The results of this study highlight why multi-scale temporal synergies of power mixes should be considered in RE system planning from the start.

“…Storage design is indicated to play significant role in enhancing demand matching capability of variable generators output [12,15,16]. These sections are exploring the minimum network storage requirement as we increase the variable generator capacity as discussed in Section 2.2.1.…”

“…Due to its ability to produce low carbon electricity, integrating variable generators to electricity grid has attracted significant worldwide research attention. The dominant question of interest is as regards to the ability of the existing grid to accommodate their variable output as we increase system size [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. In the low to high penetration of energy from these resources, such approach could help us understand the technical and economic value of these technologies [1][2][3][4][5][6][7][8][9][10].…”

TitleInvestigating the impact of wind-solar complementarities on energy storage requirement and the corresponding supply reliability criteria b s t r a c tWe present a result of hourly simulation performed using hourly load data and the corresponding simulated output of wind and solar technologies distributed throughout the state of California. We examined how we could achieve very high-energy penetration from intermittent renewable system into the electricity grid. This study shows that the maximum threshold for the storage need is significantly less than the daily average demand. In the present study, we found that the approximate network energy storage is of the order of 186 GW h/22 GW (approximately 22% of the average daily demands of California). Allowing energy dumping was shown to increase storage use, and by that way, increases grid penetration and reduces the required backup conventional capacity requirements. Using the 186 GW h/22 GW storage and at 20% total energy loss, grid penetration was increased to approximately 85% of the annual demand of the year while also reducing the conventional backup capacity requirement to 35 GW. This capacity was sufficient to supply the year round hourly demand, including 59 GW peak demand, plus a distribution loss of about 5.3%. We conclude that designing an efficient and least cost grid may require the capability to capture diverse physical and operational policy scenarios of the future grid.

“…The limited ability of the electricity grid to rely on renewable energy is evident from the facts that, for at least two of the past ten years, the peak demand occurred during evening hours in winter (when there is no solar-based generation) and the peak demand during the summer extended (albeit with a slight decrease) late into the evening hours. In addition, it is necessary to take into consideration the flexibility of the grid [ 5 ] using the Flexibility Factor ( ff ),

which ranges, as calculated, between approximately 0.65 and 0.8 with L min⁡ and L max⁡ being the maximum and minimum loads in a given year. Grid flexibility determines, according to a specific model, the scope of renewable energy the grid can contain, taking into account its required operational (ramping) costs, without the need to disconnect and “dump” a portion of the electricity.…”

The paper focuses on the quantitative analysis of Israeli Government's targets of 10% renewable energy penetration by 2020 and determining the desired methodology (models) for assessing the effects on the electricity market, addressing the fact that Israel is an electricity island. The main objective is to determine the influence of achieving the Government's goals for renewable energy penetration on the need for backup in the Israeli electricity system. This work presents the current situation of the Israeli electricity market and the study to be taken in order to assess the undesirable effects resulting from the intermittency of electricity generated by wind and solar power stations as well as presents some solutions to mitigating these phenomena. Future work will focus on a quantitative analysis of model runs and determine the amounts of backup required relative to the amount of installed capacity from renewable resources.
