“…A more profitable use of renewable energy generation can be achieved through a variety of storage techniques [20]. Energy storage technologies that are easily scalable and modular with long lives and low maintenance may be the most suitable options for distributed systems [21]- [23]. The results presented in [24] show that a PV/battery/diesel hybrid system is more efficient and reliable than other analyzed configurations: a PV plant with battery storage system and a diesel-only system.…”

Photovoltaic Water Pumping: Comparison Between Direct and Lithium Battery Solutions

et al. 2021

This work presents the conversion of a photovoltaic water pumping system (PVWPS) to its corresponding battery-based solution, while maintaining the components of the PVWPS facility and adding the power converter needed to manage the operation of a lithium-ion battery. A complete analysis of the direct PVWPS is performed based on the values obtained by the monitoring system developed for the installation. The efficiencies and performance ratios of the various elements of the facility are calculated, as well as other relevant factors (such as irradiance thresholds). The dependence of some variables on the solar resource is analyzed to model the system. A similar study is carried out in the battery-based solution and a comparative analysis of the two modes of operation is then performed to find which aspects could be improved in the battery-based solution to increase the pumping time and total daily pumped volume. The results presented demonstrate the benefits of including a battery (reduction in start/stop cycles and improved performance on cloudy days). Aspects that can be improved to make the battery-based solution more efficient and achieve better results are suggested.INDEX TERMS Photovoltaic water pumping systems, lithium batteries, battery-based pumping, water pumping, stand-alone photovoltaic system, sustainable development goals.

“…There is also literature that considers generic processes with a more abstract focus 33,34 . For an overview of the field, we refer to recent review articles 5,3,35 . As mentioned before, the approaches presented assume given electricity prices, and their DR activities might suffer from the mismatch between grid assumptions and actually implemented demand depicted in Figure 1.…”

A decoupling strategy for protecting sensitive process information in cooperative optimization of power flow

et al. 2021

Optimal power flow (OPF) with close cooperation between the power grid and flexible electricity‐intensive chemical processes can reduce costs for the grid and for electricity users. However, this would require sharing detailed chemical process models, which may reveal confidential information and potentially jeopardize competitive advantages for a chemical process operator. We propose an algorithm that enables economically advantageous cooperation without the need to exchange sensitive information. Low‐order linear models are used to represent the dynamic behavior of electricity‐intensive processes. We integrate these models into the OPF problem and solve the problem using a decoupling strategy based on Benders‐type cuts. The cuts introduce limited communication between the chemical processes and the grid without exchanging explicit information pertaining to the process dynamics and performance. Our results reproduce solutions obtained by sharing detailed process models up to a user‐defined optimality gap for several test cases that reflect both normal and congested grid states. We also investigate the trade‐off between the value of the optimality gap and computational effort. Finally, we study the scaling behavior of the iterative procedure with respect to flexible loads at multiple grid locations.

“…Energy storage plays a vital role in ensuring the flexible operation of power systems [2]. Energy storage systems (ESSs) are used in various ways, from utility-scale applications such as black start [3,4], voltage regulation [5,6], grid fluctuation suppression [7,8], and spinning reserve [9,10], to demand-scale applications such as demand flexibility management [11,12] and energy bill reduction [13,14]. An ESS stores the surplus energy and discharges the stored energy according to operational purposes.…”

Risk-Based Virtual Energy Storage System Service Strategy for Prosumers

The high cost of an energy storage system (ESS) is a barrier to its use. This paper proposes a risk-based virtual ESS (VESS) service strategy for prosumers. The basic concept of the VESS service is to logically refer to a physical ESS by multiple users. The VESS service can install ESS with a larger capacity compared to the case of installing ESS individually. Therefore, the VESS reduces the cost barrier through economies of scale. Moreover, ESS is not always being utilized at its maximum in the VESS service. Considering the risk, a VESS can offer a greater capacity than an installed ESS capacity. In this paper, the VESS service model suggested considers not only the economic benefit of increasing the VESS installation capacity but also the value at risk arising from servicing a greater capacity. The VESS service problem is formulated as a convex problem according to the VESS installation capacity and service price by applying stochastic approximation and is optimally solved using the gradient descent method in an iterative manner. The simulation results demonstrate that, when the proposed service strategy is used, the service provider that considers the risk achieves a significantly greater economic benefit of around 30% for the 128-prosumer pair case as compared to the one that does not consider risk. The benefit of the prosumer is increased by approximately 3.5% for the 128-prosumer pair case because the mismatched quantity is reduced during the peer-to-peer energy transaction. In addition, it is discussed how the proposed VESS service strategy achieves benefit through unit ESS cost reduction by the economics of scale and achieves increased service capacity with the multi-user diversity gain of participants.
