Special Issue Information

Dear Colleagues,

Many governments have set promising renewable targets. One of the main technologies available to fulfil these targets is rooftop and ground-mounted solar PV plants connected to the distribution network. However, their high penetration is hindered by technical issues such as voltage, line loading, protection, and power quality violations against the utility practices and relevant standards; as well as social issues such as poor acceptance, fear of changing operational paradigms, lack of awareness of the benefits of using PV, and ineffective communication between involved parties. This call is for original contributions to the following areas.

On the technical front:

  1. The impact of higher penetration of solar PV plants on distribution networks;
  2. Mitigation measures to minimize network impacts;
  3. Standards and good practices in place to plan and operate distribution networks with a high penetration of solar PV;
  4. Centralized and decentralized controllers for overcoming grid impacts;
  5. IoT-based control strategies available for coordinated control of assets connected to the distribution network;
  6. Enabling technologies: EV G2V and V2G operation, demand-side management, power electronic devices, energy storage.

On the social front:

  1. Reasons for varying the consumer adoption of PV under different social settings;
  2. Drives and barriers for PV-based community energy systems;
  3. Resistance to change for new technology.

This paper aims at presenting a novel effective approach to probabilistic analysis of distribution power grid with high penetration of PV sources. The novel method adopts a Gaussian Mixture Model for reproducing the uncertainty of correlated PV sources along with a piece-wise-linear approximation of the voltage-power relationship established by load flow problem. The method allows the handling of scenarios with a large number of uncertain PV sources in an efficient yet accurate way. A distinctive feature of the proposed probabilistic analysis is that of directly providing, in closed-form, the joint probability distribution of the set of observable variables of interest. From such a comprehensive statistical representation, remarkable information about grid uncertainty can be deduced. This includes the probability of violating the safe operation conditions as a function of PV penetration. Full article

Voltage control in modern electric power distribution systems has become challenging due to the increasing penetration of distributed energy resources (DER). The current state-of-the-art voltage control is based on static/pre-determined DER volt-var curves. Static volt-var curves do not provide sufficient flexibility to address the temporal and spatial aspects of the voltage control problem in a power system with a large number of DER. This paper presents a simple, scalable, and robust distributed optimization framework (DOF) for optimizing voltage control. The proposed framework allows for data-driven distributed voltage optimization in a power distribution system. This method enhances voltage control by optimizing volt-var curve parameters of inverters in a distributed manner based on a cellular computational network (CCN) representation of the power distribution system. The cellular optimization approach enables the system-wide optimization. The cells to be optimized may be prioritized and two methods namely, graph and impact-based methods, are studied. The impact-based method requires extra initial computational efforts but thereafter provides better computational throughput than the graph-based method. The DOF is illustrated on a modified standard distribution test case with several DERs. The results from the test case demonstrate that the DOF based volt-var optimization results in consistently better performance than the state-of-the-art volt-var control. Full article

Photovoltaic (PV) system installation has encouraged to be further expedited to minimize climate change and thus, rooftop solar PV systems have been sparkled in every corner of the world. However, due to technological constraints linked to voltage and currents, the PV hosting capacity has been substantially constrained. Therefore, this paper proposes a competent approach to maximize PV hosting capacity in a low voltage distribution network based on voltage control and dynamic line rating of the cables. Coordinated voltage control is applied with an on-load tap changing transformer, and reactive power compensation and active power curtailment of PV inverters. A case study with probabilistic and deterministic assessments is carried out on a real Sri Lankan network to show how the PV hosting capacity is constrained. The findings revealed the capability of integrated voltage control schemes and dynamic line rating in maximizing hosting capacity. The study is expanded by incorporating the PV rephasing approach in conjunction with the aforementioned control techniques, and the effectiveness of PV-rephasing is clearly demonstrated. When compared to voltage control and conductor static rating, the combined rephasing, voltage control, and DLR yielded a 60% increase in PV hosting capacity. Full article
