Activity Report of the Committee of a Nuclear Fusion Reactor and its Control Technology Investigation

Hirotaka Chikaraishi

Released: September 01, 2017

P598-601

All of the nuclear fusion experimental devices that have been constructed and operated so far were experimental apparatuses intended for experiments in the field of plasma physics and engineering. On the other hand, the nuclear fusion prototype reactor, which is planned to be designed and constructed in the future are plants that generate power and supply electricity. Because of this difference, control technology as a plant which is not required in the experimental equipment is required. The committee aims to contribute to future technology development towards a practical reactor by investigating and examining the plant and its control technology required after the prototype reactor.

Economic Analysis for Microgrid through Price-based Demand Response

Tianhu Ma, Jumpei Baba, Yumiko Iwafune

Released: September 01, 2017

P602-613

In this paper, we developed Unit Commitment model based on IEEJ EAST 10 Machine system model parameters, and constructed the Day-ahead market and Hour-ahead market. We analyzed the impact of PV penetration on both of Utility side and Microgrid side by the optimization of scheduling of utility side and Microgrid side respectively. We analyzed the impact of PV penetration on scheduling variation of pump generator and thermal power generator for utility, impact on variation of marginal energy market price, and analyzed the impact of variation of marginal energy market price on microgrid scheduling. Moreover, by the price-demand mode, Through Day-ahead market and Hour-ahead market, we analyzed the interaction effect of scheduling result for utility and microgrid each other. And last, we calculated and evaluated the fuel cost for both utility and microgrid in case of with market and without market respectively, and concluded that scheduling result for both of utility side and microgrid have been improved, the win-win result that total cost is low than without microgrid response has been verified.

Development of Electromagnetic Transient Simulation Models for Power Quality Analysis of Distribution Systems

Tomohiro Nagashima, Kentaro Fukushima, Taku Noda

Released: September 01, 2017

P614-622

Due to the rapid spread of renewable energy power sources in recent years, voltage rise problems in distribution systems caused by reverse power flow from these renewable energy power sources especially from photovoltaic (PV) power generation systems are of great concern. To cope with this kind of problems, conventional voltage regulation devices such as load-ratio transformers (LRTs) in the substation and step voltage regulators (SVRs) on the distribution line are basically used. If their voltage regulation capability is not sufficient, the power conditioning systems (PCSs) of PV power generation systems may be modified so as to supply reactive power and a static synchronous compensator (STATCOM) may be applied to the distribution system. Therefore, the coordination of these conventional and new voltage regulation devices is necessary for the design of smarter distribution systems, and electromagnetic transient (EMT) simulations of distribution systems with these devices have to be carried out to assess power quality. To this end, the authors have developed EMT simulation models of distribution substations, SVRs and distribution STATCOMs, and they are routinely used for power quality assessment studies. This paper presents these simulation models and a simulation example.

Estimate of Looking Back Impedance of Photovoltaic Power Generation Connected to Low-voltage Line

Toshiya Nanahara, Dai Inose, Tatsuki Okamoto

Released: September 01, 2017

P623-631

The paper examines the looking back impedance of photovoltaic power generation (PV) connected to a low voltage line. Although the impedance is one of the vital factors in managing voltage profiles of a power system, few studies have been reported on the impedance. This paper proposes two estimation methods of the impedance using regression and spectral analyses techniques. Since a power factor for the PVs under study is assumed to be unity, the resistance component of the impedance is estimated with the methods. The methods are applied to the actual data obtained for 28 PVs. The estimated resistance with the two methods closely agrees with each other; this implicates the validity of the estimate. The estimates show that the looking back resistance exhibits more than one order difference among the PVs and tends to be smaller for a PV connected to a three phase three wire system than for that connected to a single phase three wire system. The seasonal variations of the resistance are also discussed in this paper.

Cost-effective Methodology for Grid Stabilization to Introduce Renewable Energy in Micro-grid

Tadayuki Ogawa

Released: September 01, 2017

P632-636

The integration of Renewable Energy (RE) with existing Diesel Engine Generators (DEGs) is rapidly promoted to reduce the dependency on fossil fuels and improving the energy security in many Small Island Developing States (SIDS). This paper proposes the cost-effective methodology for grid stabilization to introduce RE in Micro-grid, through evaluating Levelized Cost of Electricity (LCOE) under increasing RE penetration.

Theoretical Investigation of the Most Suitable Capacity of Latent Heat Accumulation Introduced into a Thermoelectric Power Generation System

Hokuto Yamada, Akira Tsuyoshi

Released: September 01, 2017

P637-638

Recently thermoelectric power generation has attracted attention for waste heat recovery in the incineration facilities. However, it has not come into practical use yet because thermoelectric power generating modules cost is still high. Therefore, to reduce generation cost, latent heat accumulation installed thermoelectric power generating system is proposed and theoretically evaluated. In this study generating cost is reduced from 34.2yen/kWh to 32.5yen/kWh by installation of a latent heat accumulator into the incinerator thermoelectric power generation.

Suppressing Voltage Rises by Autonomous Decentralized Reactive Power Control of Cell Grid

Satoshi Takayama, Tomohisa Maruyama, Atsushi Ishigame

Released: September 01, 2017

P639-640

Recently, installation amount of Photovoltaic generation for distributed network is increased with the enforcement of Feed in Tariff. As a result, voltage rises of distributed network has become a problem. The author has proposed Cell Grid for the purpose of contributing to system stabilization control by some customer. In this paper, we propose the suppressing method of voltage rises by autonomous decentralized reactive power control of Cell Grid.

A Study of Load Flow Analysis Considering PV Output Forecast Error

Masaomi Yanagida, Atsushi Ishigame

Released: September 01, 2017

P641-642

This paper describes a load flow analysis considering PV output forecast error using interval arithmetic. We can simply set the PV output as interval value with upper and lower limits and evaluate the ranges of nodal voltage magnitude, angle and line power flow. Simulation results show validity of described method by comparing with Monte Carlo Simulation and typical load flow.
