“…Definition of terms: Demand-side management (DSM) -This is a proactive approach of demand management mechanisms aimed at making the electricity consumers' energy-demand efficient in the long-term. Demand-side management also describes various measures that can be taken on the customer side for energy efficiency or conservation purposes [2,9]. Designing of power pooling scheme falls under this method of demand management mechanisms.…”

“…Electricity occupies a top position in the energy hierarchy; and just like every other vital commodity, should be subject to efficient management. In these days of deregulated electricity market in Nigeria, much attention has been paid to management and optimization of power generated and power consumed on the demand-side within the interconnected grid system [2]. This is because, to practically meet all the energy demand from the end users, the grid system must be designed such that it should satisfy the peak power demand at all times [3]; which is presently not realizable in this part of the world due to imbalance in energy demand and supply.…”

The design of a power pool scheme for demand-side management of co-located banks in Owerri metropolis, Nigeria has been carried out in this work. The paper addressed the problem of matching instantaneous load demand with appropriate generator capacities which results from dynamic nature of small and medium scale industrial load, such as co-located banks. It also aimed at proffering solutions to health and environmental problems associated with use of scattered single generators per firm. A model for interconnection of generators and loads in a pool structure was developed to form a ring network, analogous to a typical power system. One of the generators in the pool was chosen as the slack bus and the other generators and load buses were arranged in the power pool arrangement such that Newton-Raphson's method could be applied in load flow analysis. With this modeling and application of appropriate schedule, a cooperative pooling model was developed such that only the exact generating capacities were deployed. The proposed model was simulated by paralleling three 200kVA generator units in a synchronized ring network to serve the entire five banks. Results from the load flow analysis showed that the per unit voltage magnitudes at buses 1, 2, 3, 4 and 5 were 1.000, 0.997, 1.000, 0.998 and 1.000 respectively, while voltage mismatch angles (degree) were also gotten as 0.000, 0.003, 0.024, 0.060 and 0.086 respectively for the buses 1 to 5. From the cost benefit analysis carried out, the benefit-cost ratio (BCR) of 1.965 was calculated, which showed that this project will be very beneficial to the cooperating banks. Scheduling the operations of the three generators using mathematical permutation and combination model showed that the total man-hour of the plant operators is reduced by 40%. Also, applying the greenhouse gases emissions cost model it was found that the carbon footprints i.e. greenhouse cost for the interconnected network is reduced by 40%.

“…The cement industry load was modeled as a shifting load to reduce the operating cost of the enterprise [7]. Wood industry loads were also believed to be qualified potential regulating service suppliers based on a case analysis [8]. The regulation capability of metal casting industry loads in participating in the ancillary market was studied too [9].…”

A Practical Load-Source Coordinative Method for Further Reducing Curtailed Wind Power in China with Energy-Intensive Loads

Large-scale wind power farms in China are suffering from large amounts of curtailed wind power in the conventional dispatching mode. Energy-intensive loads have great potential in providing service regulation to help consume the curtailed wind power. However, constrained by technical limitations, the regulating power of energy-intensive loads cannot fully follow the fluctuating wind power. This would result in insufficient utilization of the regulation capability of energy-intensive loads, which limits the promotion in consumption of curtailed wind power brought by load-source coordination. With this concern, a brand new method for further consuming the curtailed wind power, which involves using coal-fueled units to provide ancillary regulation for the coordination of energy-intensive loads and wind power is presented, and a corresponding bi-level coordinative model is also established. The first level of optimization is intended to maximize the consumption of curtailed wind power with minimum ancillary regulation energy. The second level of optimization is to allocate the ancillary regulating power with minimum regulation cost. Wind power consumption was increased by 3,369.25 MWh and utilization rate of energy-intensive loads was promoted to 100% in the case analysis, which verifies the effectiveness of the proposed method.

“…Squaring up to interruptible loads and electric vehicles aggregated by LAs, the simultaneous dispatch is proposed, and aiming at the uncertainties of wind and photovoltaic (PV) powers, a developed two-stage model is presented to reduce the operation cost of a microgrid in [13]. Due to the relatively high regulating capacity of high-energy loads represented by the wood industry [14,15], in terms of local accommodation, the paper presents a joint operation mode of a high-energy load and wind power. However, the fact that high energy loads distribute regionally narrows the applicable range of those models [16].…”

With the support of a smart grid, a load aggregator (LA) that aggregates the demand response resources of small-and medium-sized customers to participate in the electricity market would be a novel way to promote wind power accommodation. This paper proposes a wind farm-LA coordinated operation mode (WLCOM), which enables LAs to deal with wind farms directly at an agreement price. Afterwards, according to the accommodation demand of the wind farm, a coordinated dispatch model taking advantage of the various response capabilities of different flexible loads is set up to maximize the revenue of the LA. A case study was conducted to demonstrate the effectiveness of the proposed WLCOM and the coordinated dispatch model. The demonstration indicates that: (a) load fluctuations and wind curtailment were obviously reduced; and (b) both the LA and the wind farm participating in coordinated operation obtained higher revenues. Factors that influence the accommodation level, as well as revenues of wind farms and LA, are also investigated.
