Optimal Management of Seasonal Pumped Hydro Storage System for Peak Shaving

چکیده
Power demand varies on a daily and seasonal basis. Responding to changing demands over time is challenging for energy suppliers as it causes expensive power plants operate in high-demand seasons, usually summer, increasing the cost of electricity. Peak load shaving makes curve flatten by reducing peak shifting times lower demand, hence operation plants. Hence, there need large-scale long-term ESS store low-demand seasons future utilization highest-demand ones. In this work, an management system (EMS) developed optimally manage grid-connected pumped hydro storage (PHS) shaving. The proposed model incorporates dynamic economic dispatch (DED) study period one year; hence, DC flow analysis considering transmission constraints utilized ensure fast estimation manageable simulation time. framework can be adopted assess profitability PHS-utilizing GAMS optimization tool. Further, draw conclusions that would suit characteristics pattern. This essential motivate construction new PHS due high costs they are identified with, especially geographical areas where technology not yet considered or hard construct. results demonstrate integrating 1500 MWh reduced thermal units 1224 annually. reduction was recorded after unit ranged from 2.6 M 22 USD/year, depending capacity.

Peak Shaving Control Method for Energy Storage
Peak Shaving is one of the Energy Storage applications that has large potential to become important in the future’s smart grid. The goal of peak shaving is to avoid the installation of capacity to supply the peak load of highly variable loads. In cases where peak load coincide with electricity price peaks, peak shaving can also provide a reduction of energy cost. This paper addresses the challe...
متن کاملOptimal Sizing and Control of Battery Energy Storage System for Peak Load Shaving
Battery Energy Storage System (BESS) can be utilized to shave the peak load in power systems and thus defer the need to upgrade the power grid. Based on a rolling load forecasting method, along with the peak load reduction requirements in reality, at the planning level, we propose a BESS capacity planning model for peak and load shaving problem. At the operational level, we consider the optimal...
متن کاملShort-term peak shaving operation for multiple power grids with pumped storage power plants
The East China Power Grid (ECPG) is the biggest regional power grid in China. It has the biggest installed capacity of pumped storage power plants (PSPPs) and is responsible to coordinate the operation of its five provincial power grids. A recent challenge of coordinating operations is using PSPPs to absorb surplus energy during off-peak periods and generate power during peak periods. Differing...
