“…However, solar and wind energy sources (also called Variable Renewable Energy Sources, VRES) present some challenges for the management of the power sector (as summarized in (Albadi and El-Saadany, 2010) for wind power and (Komiyama and Fujii, 2014) for solar power). They are variable across several time-scales: years, seasons, days, hours and even less.…”

In this paper we demonstrate the role of electricity storage for the integration of high shares of Variable Renewable Energy Sources (VRES 3 ) in the long-term evolution of the power system. For this a new electricity module is developed in POLES (Prospective Outlook on Long-term Energy Systems). It now takes into account the impacts of VRES on the European power system. The power system operation relies on EUCAD (European Unit Commitment And Dispatch), which includes daily storage and other inter-temporal constraints. The innovative aspect of our work is the direct coupling between POLES and EUCAD, thus combining a long-term simulation horizon and a short-term approach for the power system operation. The storage technologies represented are pumped-hydro storage, lithium-ion batteries, adiabatic Compressed Air Energy Storage (a-CAES) and electric vehicles (charging optimisation and vehicle-to-grid). Demand response and European grid interconnections are also represented, in order to include to some extent these flexibility options.

“…Cap min,VRE ≤ Cap VRE (14) where • LFC constraints LFC is important to maintain the frequency of the power grid so that concerns to the LFC issues have been addressed in various power system models and control techniques/strategies [20]. In this study, the constraints on LFC expressed in Equations (15)- (22) were taken from the literature [21,22] that is used by Japanese electric power companies to estimate the potential capacity of wind power that can be connected to the power grid.…”

Evaluating the Potential of Variable Renewable Energy for a Balanced Isolated Grid: A Japanese Case Study

Abstract:There is a global push to develop renewable energy to further a low-carbon society. However, the nature of variable renewable energy (VRE) sources such as wind power and solar photovoltaic (PV) systems may create problems because electricity grids require a stable power supply to match demand. To evaluate the potential capacity of VREs that may be installed, we develop an optimized model that balances power supply and demand and also considers grid balancing by battery storage and load frequency control. The model was applied to a case study of an isolated grid on a remote Japanese island. When set to optimize the grid in terms of lowest cost, the model suggested that, compared with the base case, the capacity of wind power should be increased by a factor of 1.7 and 15.8 for situations without and with battery storage, respectively. Since it was always considered to be more expensive than wind power, no change in solar PV capacity was observed. These approaches resulted in a decrease in the total power generation cost of 2% and 24%, respectively, while total CO 2 emissions fell by 3% and 52%, primarily driven by decreased used of the existing fossil-fueled thermal plant.

“…In case of Japan, among RESes, the adoption of photovoltaics (PVs) and wind turbines (WTs) has rapidly increased following the issuance of feed-in tariff (FIT) in July 2012 [3]. As the end of 2015, over 25 GW of these RESes have been introduced throughout Japan [4], and vigorous efforts are underway to achieve the Japanese government's PV2030+ goal [5], instituted before the Tohoku great earthquake (11 March 2011), on an accelerated schedule. However, as PVs and WTs use natural energy as their primary energy source, their output fluctuates.…”

Annual Assessment of Large-Scale Introduction of Renewable Energy: Modeling of Unit Commitment Schedule for Thermal Power Generators and Pumped Storages

Abstract:The fast-increasing introduction of renewable energy sources (RESes) leads to some problems in electrical power network due to fluctuating generated power. A power system must be operated with provision of various reserve powers like governor free capacity, load frequency control and spinning reserve. Therefore, the generator's schedule (unit commitment schedule) should include the consideration of the various power reserves. In addition, it is necessary to calculate the annual operational costs of electric power systems by solving the unit commitment per week of thermal power generators and pumped storages in order to compare and examine the variance of the operational costs and the operating ratio of the generators throughout the year. This study proposes a novel annual analysis for the thermal power generator and pumped storages under a massive introduction of RESes. A weekly unit commitment schedule (start/stop planning) for thermal power generator and pumped storages has been modeled and calculated for one year evaluation. To solve the generator start/stop planning problem, Tabu search and interior point methods are adopted to solve the operation planning for thermal power generators and the output decision for pumped storages, respectively. It is demonstrated that the proposed method can analyze a one-year evaluation within practical time. In addition, by assuming load frequency control (LFC) constraints to cope with photovoltaic (PV) output fluctuations, the impact of the intensity of LFC constraints on the operational cost of the thermal power generator has been elucidated. The increment of the operational cost of the power supply with increasing PV introduction amount has been shown in concrete terms.
