“…This filter may be L, LC or LCL type depends upon application of ES. Non-critical load can be: resistive, capacitive, inductive or customer loads like water heater [26], air conditioning unit [27], and thermal storage [28]. It can tolerate the voltage fluctuation.…”

<span lang="EN-US">Decarbonizing power generation and reducing greenhouse gas emissions require renewable energy sources. Intermittent nature of renewable energy sources can cause blackouts, fluctuation in voltage, grid-connected inverter usage, inability to predict power generation, fluctuations in voltage and frequency. It is possible to balance between the supply and demand of power to overcome these problems by using an electric spring (ES). It is necessary to study its work, types, and controlling actions for realizing the benefits of the electric spring. This paper reviews the hardware structure of an ES based on voltage-source inverter (VSI) and current-source inverter (CSI) topologies, in single-phase and three-phase AC power distribution systems with renewable energy sources. The structure, control strategies, operating modes, advantages and disadvantages of each ES topology are elaborated to make it a suitable alternative for resolving different power quality issues caused due to the high penetration of renewable energy sources.</span>

“…References [14]- [16] carried out a series of researches on SLs based on electric springs (ESs). ESs can support voltage and realize power quality improvement as its ancillary function, as well as to reduce energy storage requirements [4], [17]. The corresponding active and reactive operating ranges of ES-2 and BTB-ES connected to different types of non-critical loads under the constraints of ES's inverter power, voltage and current are analyzed in [18].…”

The multiple uncertainties caused by high penetration renewable energy sources (RESs) and loads access place demanding requirements on the flexibility of distribution networks. To optimize the flexible sources, a multi-time scale flexible dynamic optimization model is proposed based on active distribution network (ADN) with smart loads participation. The long-timescale stage aims to reduce the comprehensive cost and smooth the net load fluctuations. In this stage, two indicators, namely, scheduling cost and remaining scheduling capacity ratio are designed to update the output order of dynamic regulation equipment (RESs, energy storage systems). Meanwhile, interruptible load curtailments are also coordinated in the power generation plan. Using the net load fluctuations constraint, the flexibility margin for ADN is more sufficient. In the short-term-scale stage, smart loads are introduced to utilize the load-side demand response potential and expand the margin of flexibility. For consumers, a win-win cooperation between ADN and users can be achieved with utility model, which guaranteed the reliable regulation capacity to support better power quality. And for ADN, the economic costs are further reduced, along with the elimination of the voltage violation. Case studies are conducted to demonstrate the performance of the proposed strategy.

“…This flexibility can be achieved by means of two possible mechanisms: demand-side response (DSR) and/or energy storage systems (ESS). The first one had a wide attention in literature [15,16]. As household electricity demand has a limited potential to apply restrictive DSR programs, the work described in this paper is focused on ESS usage instead, whose operation is scheduled according to different targets.…”

Advantages of Minimizing Energy Exchange Instead of Energy Cost in Prosumer Microgrids

et al. 2019

Microgrids of prosumers are a trendy approach within the smart grid concept, as a way to increase distributed renewable energy penetration within power systems in an efficient and sustainable way. Single prosumer individual management has been previously discussed in literature, usually based on economic profit optimization. In this paper, two novel approaches are proposed: firstly, a different objective function, relative to the mismatch between generated and demanded power, is tested and compared to classical objective function based on energy price, by means of a genetic algorithm method; secondly, this optimization procedure is applied to batteries’ coordinated scheduling of all the prosumers composing a community, instead of single one, which better matches the microgrid concept. These approaches are tested on a microgrid with two household prosumers, in the context of Spanish regulation for self-consumption. Results show noticeably better performance of mismatch objective function and coordinated schedule, in terms of self-consumption and self-sufficiency rates, power and energy interchanges with the main grid, battery degradation and even economic benefits.
